Each angle of the equilateral triangle in the figure has measure (2x – 9)°. Determine the value of x.
A) x = 25.5
B) x = 34.5
C) x = 69
D) x = 60
Answers
Answer:
34.5
Step-by-step explanation:
An easy way to find this out is plug in all the answers into our equation until we get 180. So here's what you do:
A) X=25.5
So put that in the equation replacing x like this : 2(25.5)-9 =42 then multiply by three which = 126, So, A) is not our answer, now do it with the rest until you get 180,
2(34.5)-9=60 60x3=180 so your answer will be the number you plug in aka:34.5
Hope this helps you understand the topic a little better <3

What is the slope of a line that is perpendicular to a line that has a slope of -7
Please help ya girl out :))
Answers
The slope of a perpendicular line will be the opposite of the first slope given. So since the first slope is -7 then we make the negative positive and flip the numerator and denominator. So -7/1 will be 1/7
In triangle ABC, we can draw a perpendicular line segment from vertex C to segment AB. The intersection of AB and the perpendicular is called E. We know that BE is the shortest distance from B to and that is the shortest distance from A to CE because of the shortest distance theorem. Therefore, BC > BE and AC > AE. Next, add the inequalities: BC + AC > BE + AE. Then, BE + AE = BA because of the . Therefore, BC + AC > BA by substitution.

Step-by-step explanation:
Answer:
x = [tex]\frac{a-c}{b}[/tex]

Which exponential function is represented by the graph?
O f(x) = 2( 1/2 )x
O f(x) = 1/2(2)x
O f(x) = 1/2(1/2)x
Of(x) = 2(2)x
PLEASE HELP MEE!
Answers
Answer:
f(x) = [tex]\frac{1}{2}[/tex] [tex](2)^{x}[/tex]
Step-by-step explanation:
Using the standard form of the exponential function
y = a [tex]b^{x}[/tex]
To find a and b , substitute ordered pairs from the graph
Using (0, 0.5 ), then
0.5 = a[tex]b^{0}[/tex] [
a = 0.5 , so
y = [tex]\frac{1}{2}[/tex] [tex]b^{x}[/tex]
Using (1, 1) , then
1 = [tex]\frac{1}{2}[/tex][tex]b^{1}[/tex] , thus
b = 2
f(x) = [tex]\frac{1}{2}[/tex][tex](2)^{x}[/tex] ← exponential function representing graph

what is 5 1/6 - 7 1/3
Answers
Answer:
-13/6 or -2 and 1/6 or -2.16
Step-by-step explanation:
The solution of expression in mixed fraction form is,
⇒ 2 1/6
We have to simplify the expression,
⇒ 5 1/6 - 7 1/3
Firstly we can change it into improper fraction,
⇒ 5 1/6 - 7 1/3
⇒ 31/6 - 22/3
Make denominator same by taking LCM of 6 and 3 which is 6,
⇒ 31/6 - 44/6
⇒ (31 - 44) / 6
⇒ 13/6
⇒ 2 1/6
Therefore, The solution of expression in mixed fraction form is,
⇒ 2 1/6

If tan x = m, what is sin x in terms of m?
Answers
Answer: m/sqrt(m^2)+1
Step-by-step explanation: if tan x = m, then the opposite angle is m and the adjacent angle is 1 so 1 squared plus m squared equals c squared. c = sqrt (1 + m^2)
sin x = opposite/hypotenuse = m/sqrt(m^2)+1
The value of sin x in terms of m is [tex]\frac{m}{\sqrt {m^2+1}}[/tex]
Trigonometry are identities used to express the sides and angles of a triangle.
According to SOH CAH TOA,
Tan θ = Opposite/Adjacent
Given that tan x = m
Opposite = m
Adjacent = 1
Get the hypotenuse using the pythagoras theorem
Hyp² = Opp² + Adj²
Hyp² = m²+1²
Hyp² = m²+1
Take the square root of both sides
√Hyp² =√m²+1
Hypotenuse = √m²+1
Next is to get sin x:
Sin x = Opposite/Hypotenuse
Sin x = [tex]\frac{m}{\sqrt {m^2+1}}[/tex]
Hence the value of sin x in terms of m is
[tex]\frac{m}{\sqrt {m^2+1}}[/tex]
