Answer:
62 degrees
Step-by-step explanation:
If two angles are complementary, it means that their sum is 90degrees
Hence if m<a and m<b are complementary, then;
m<a + m<b = 90
Given
m<a = 28degrees
Required
m<b
Substitute into the formula as shown;
28 + m<b = 90
m<b = 90 - 28
m<b = 62degrees
Hence the measure of angle b is 62 degrees
Answer:
Angle B: 62
Step-by-step explanation:
90 degrees minus angle a, (28 degrees) to get 62 degrees.

A. -√3 +2
B. √2*√3
C. √27*√ 3
D. 3√7 + 2√7-5√7
Answer:
A and B.
Step-by-step explanation:
The irrational number are -√3 +2 and √2 x √3.
What is Irrational Number?Any number that cannot be stated as a fraction for any integers is considered to be irrational. The decimal expansions of irrational numbers are neither periodic nor do they come to an end. Every number that is transcendental is illogical.
Given:
A) -√3 +2 is an irrational number.
B) √2 x √3 = √6, which is an irrational number.
C) √27 x √ 3
= 3√3 x √3
= 3 x 3
= 9, which is a rational number.
D) 3√7 + 2√7-5√7

A polynomal of degree of 2 that has zeros -4 and 2 is
9514 1404 393
Answer:
f(x) = x^2 +2x -8
Step-by-step explanation:
If p and q are zeros of a quadratic, its factored form is ...
f(x) = (x -p)(x -q)
For your zeros, the factored form is ...
f(x) = (x +4)(x -2)
Expanded using the distributive property, this is ...
f(x) = x(x -2) +4(x -2) = x^2 -2x +4x -8
f(x) = x^2 +2x -8

10x +17y = -89
-(10x + 14y = - 68)
3y = -21
y = -7
5x + 7(-7) = -34
5x -49 = -34

7x-y=19
2x-3y=19
Answer:
2x + y = -2, x + 2y = 2
4x + y - 2z = 0, 2x+ 3z = 9 , -6x - 2y + z = 0
x + y = 4 , x - y = 2
Step-by-step explanation:
Answer:
x=2 and y=−5
Step-by-step explanation:
Let's solve your system by elimination.
7x−y=19;2x−3y=19
Multiply the first equation by -3,and multiply the second equation by 1.
−3(7x−y=19)
1(2x−3y=19)
Becomes:
−21x+3y=−57
2x−3y=19
Add these equations to eliminate y:
−19x=−38
Then solve−19x=−38for x:
−19x=−38
(Divide both sides by -19)
x=2
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
7x−y=19
Substitute2forxin7x−y=19:
(7)(2)−y=19
−y+14=19(Simplify both sides of the equation)
−y+14+−14=19+−14(Add -14 to both sides)
−y=5
y=-5

What is the volume of the composite figure?
Answer:
1428 in³
Step-by-step explanation:
To find the volume of this figure, we will need to use two formulas. The volume of a Rectangular Prism [tex](A=l*w*h)[/tex] and volume of a triangular prism.
[tex](A=\frac{1}{2} (b*h )[/tex]
If we look at the Rectangular Prism, we can find that l = 17, w = 8, and h = 5. Multiply these to find the volume:
17 × 8 × 5 = 680 in³.
Solving for the triangular prism gives us:
A = 1/2 (11 × 8 × 17)
A = 748.
Add these two volumes to find the volume of the composite figure:
748 + 680 = 1428 in³

9x^2+ 3x – 2 = 0
Answer:
x=1/3, x=-2/3
Step-by-step explanation:
9x^2 +6x -3x -2=0
6x and -3x add up to 3x. You need four terms to factor.
Then you factor=
3x(3x+2)-1(3x+2)=0
(3x-1)(3x+2)=0
Then you can make two equations
3x-1=0 and 3x+2=0 because to multiply to get 0, at least one will be 0.
3x-1=0
3x=1
x=1/3
3x+2=0
3x=-2
x=-2/3
So your answers are x=1/3, x=-2/3

Express as a trinomial.
(2x+1)(x+9)
Answer:
2x^2 + 19x + 9
Step-by-step explanation:
Using the FOIL method (ask me via comments if you don't know what it is), we expand it to 2x^2 + 18x + x + 9, then we add like terms, equal to 2x^2 + 19x + 9.
The trinomial expression for (2x + 1)(x + 9) is [tex]2x^2 + 19x + 9[/tex].
To express (2x + 1)(x + 9) as a trinomial, you need to perform the multiplication.
Distribute each term from the first parenthesis to each term in the second parenthesis:
(2x + 1)(x + 9) = 2x * x + 2x * 9 + 1 * x + 1 * 9
Now, simplify the expression:
[tex]= 2x^2 + 18x + x + 9[/tex]
Finally, combine like terms:
[tex]= 2x^2 + 19x + 9[/tex]
So, (2x + 1)(x + 9) expressed as a trinomial is [tex]2x^2 + 19x + 9.[/tex]

Are the two triangles congruent ? Please answer correctly !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!
Answer
YES
Step by step Explanation
Answer:
There is not information given to assume the triangles are congruent.
Step-by-step explanation:
You can tell if two triangles are congruent by any of the following rules:
Three sides are congruent (SSS),
Two angles and a side in between are congruent (ASA)
Two sides and an angle in between are congruent (SAS)
Two angles and a side connected to one of those angles are congruent (AAS)
Note: SSA (Two Sides & One Angle) does not work. I good way to remember is that it spells a bad word backwards :)
In this case, there are only two sides given, but there aren't any angles, so there is not enough information to conclude if they are congruent or not.
