Answer:
Step-by-step explanation:
This is Isosceles triangle (look at the picture).
We know:
All triangles have internal angles that add up to 180°
Therefore:
combine like terms:
(x - 2)° and 3y° are supplementary angle (Two Angles are Supplementary when they add up to 180°).
Therefore:
substitute x = 29 and solve for y:
The 3 inside angles of a triangle need to equal 180 degrees. Looking at the larger outside triangle the top angle is 30 and the lower right angle is 60.
30 + 60 = 90
The lower left angle needs to be 180 - 90 = 90 degrees.
That angle is split into two angles with one given as 70.
This means X needs to be 90 - 70 = 20 degrees.
x = 20
Answer:
b = c(a - 6x )
Step-by-step explanation:
Given
6x + 
= a ( subtract 6x from both sides )
= a - 6x ( multiply both sides by c to clear the fraction )
b = c(a - 6x)
Answer:
Button #4. The last button. 8p = t.
Step-by-step explanation:
This is because there are 8 pieces of string, and p is equal to the length of one string, so one string times 8 is the total length of all the strings.
Answer:
x = -1
Step-by-step explanation:
x-7/4=-2
x-7=-8
x=-1
