Answer:
Step-by-step explanation:
Use the Triangular Interior Angles Theorem to figure this out:
180° = [7x + 1]° + [6x - 6]° + 55°
180° = [−5 + 13x]° + 55°
180° = [50 + 13x]°
-50° - 50°
____________
![\frac{130°}{13} = \frac{[13x]°}{13} \\ \\ 10° = x](https://tex.z-dn.net/?f=%5Cfrac%7B130%C2%B0%7D%7B13%7D%20%3D%20%5Cfrac%7B%5B13x%5D%C2%B0%7D%7B13%7D%20%5C%5C%20%5C%5C%2010%C2%B0%20%3D%20x)
You then plug this back into all three expressions to get 71° as the measure of ∠G and 54° as the measure of ∠T.

Answer:
It would be 90,000
Step-by-step explanation:
Answer:
XY = 16 ft
Step-by-step explanation:
The mid segment DE is half the sum of the parallel bases, that is
= 20 ( multiply both sides by 2 to clear the fraction )
XY + WZ = 40
XY + 
XY = 40 ( multiply through by 2 to clear the fraction )
2XY + 3XY = 80
5XY = 80 ( divide both sides by 5 )
XY = 16
Here's how you do it: you find all the distances between the three points and add them together to calculate the perimeter of the triangle. To calculate for the distance between two points, the formula is
d = √[(x2 - x1)² + (y2 - y1)²]
So, just take two points, assign x1 and x2 with corresponding y1 and y2, then you get the answer.
Points: D(1,4), E(3,-2), C(-3,1)
After substituting the answers would be:
DE = 6.3 units
CE = 6.7 units
CD = 5 units
Perimeter = 6.3 + 6.7 + 5
Perimeter = 18 units
