Answer:
Well you can either straight up subtract from the total degrees of a triangle using the sum of both of the given angles, which would equal x, or you can make an equation. I’ll do both.
180-78-51=51, x=51
78+51+x=180
129+x=180
x=180-129
x=51
The answer as a decimal is 0.32
So..to make it easier you can jut multiply by 2 on both sides...
so you get 3y-2y=8+y..
which is equal to 0=8..but because they arent equal it means that there is no solution.
Answer:
7/2
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(7 1/2 - 7 1/2)² + [-2 1/2 - (-6)]²
√(0)² + (7/2)²
√49/4
= 7/2
