Step-by-step explanation:
In triangle JKL, k = 4.1 cm, j = 3.8 cm and ∠J=63°. Find all possible values of angle K, to the nearest 10th of a degree
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.
Given a triangle with angles A, B, C and the corresponding sides opposite to the angles as a, b, c. Sine rule states that for the triangle, the following holds:
[tex]\frac{a}{sin(A)}=\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]
In triangle JKL, k=4.1 cm, j=3.8 cm and angle J=63°.
Using sine rule, we can find ∠K:
[tex]\frac{k}{sin(K)}=\frac{j}{sin(J)} \\\\\frac{4.1}{sin(K)}=\frac{3.8}{sin(63)} \\\\sin(K)=\frac{4.1*sin(63)}{3.8}\\\\sin(K)=0.9613\\\\K=sin^{-1} (0.9613)\\\\K=74.0^o \\[/tex]

Answer:
because WXYZ is a rhombus
=> WX // YZ
=> ZWX + WZY = 180⁰
=> WZY = 180⁰ - ZWX = 180⁰ - 77⁰ = 103⁰

7853.98mm
Step-by-step explanation:
Circumference is pi times diameter so the diameter is 100 millimeters
Diameter is 2 times the radius so the radius is 50 millimeters
Area is pi times the radius squared so the area is about 7853.98 millimeters squared

hi!!! what’s the area and formula for this problem??
Answer:
134.28 m²
Step-by-step explanation:
I suppose this is an isosceles triangle
tan 75° = 2 + √3 = 3.73 = h / 6 (h: height and 6 = 12/2, 1/2 of base)
h = 6 x 3.73 = 22.38
Area = (12 x 22.38) / 2 = 134.28
Solve for A.
BA + C = D
1)A = D-B-C
2)A = (D-C)/B
3)A = (C - D)B

If cos 0 = 3/5
and angle 0 is in Quadrant IV, what is the value of tan 0 ?
Tan =
Answer:
-4/3.
Step-by-step explanation:
cos O = 3/5
Using Pythagoras to find the length of the side opposite the angle O:
As the cos of O is adjacent/ hypotenuse, Hypotenuse = 5 , adjacent side = 3 so
opposite side. = sqrt(5^2 - 3^2) = sqrt 16
= 4.
Now the tangent is negative in Q IV so
tan O = opposite / adjacent side = -4/3

How does collecting like terms in an expression differ from collecting like terms in
an equation/inequality? Explain.
Answer:
I think its different from each other because maybe combining like terms in a inequality your trying to compare them? Or maybe they're just advanced. Can someone give me an example of an inequality please so I can try finding out the difference?

Answer:
I believe the answer would be A.
Step-by-step explanation:
You can get rid of B. and C. since it is in the middle. The highest would be at the top/right side and the lease would be at the bottom/left side. Then the total score does not make much sense because you would have to add up every number

1/3 radical 176xy to the 8th power
Answer:
Remove all perfect squares from inside the square root. ... I think it's about eighth or ninth grade. ... so if you have the cube root of the square root of (x-5) =2, you get ((x-5)^(1/2))^1/3 = 2, power to power requires multiplication, so (x-5)^1/6 = 2, ...
Missing: 176 xy
It took the football team 5 h to travel from Titletown, a total distance of 1320 km. Part of the trip was by bus and the remainder by plane. The bus averaged 40 km/h and the plane 600 km/h. How many hours were spent travelling by bus?
Answer:
It took 2 hours by plane
Step-by-step explanation:
let bus is represented by x and plane is represented by y
the total distance of bus and plane will be represented by equation:
40 x + 600 y = 1320 (1)
the total time taken by bus and plane will be represented by:
x + y = 5 (2)
solving equations (1) and (2) simultaneously:
Multiply by 40 on both sides in eq (2) and then subtract (1) and (2)
40 x + 600 y = 1320
40 x + 40 y = 200
_______________
560 y = 1120
y = 1120/ 56
y= 2
since plane is represented by y so, the time they spent travelling by plane is 2 hours.
