Answer:
x = 12.5
Step-by-step explanation:
The value of x is part of the value of an angle in a triangle where the other angles are known. This suggests that the relevant theorem is the "angle sum theorem," which tells you <em>the sum of angles in a triangle is 180°</em>.
This gives you the equation ...
60° +60° +(4x+10°) = 180° . . . . total of all angles is 180°
4x +130° = 180° . . . . . . . . . . collect terms
4x = 50° . . . . . . . . . . . . subtract 130° from both sides
x = 12.5° . . . . . . . . . divide both sides by 4
I believe the answer is 21. I can tell you how I got the answer if you want.
Answer:
x=2 and y=−6
sorry this is pretty long, I did not know if you needed the steps or not
Step-by-step explanation:
−2y−10=x;−10x−y=−14
Solve−2y−10=x for x
−2y−10=x
−2y−10+−x=x+−x
−x−2y−10=0
−x−2y−10+2y=0+2y
−x−10=2y
−x−10+10=2y+10
−x=2y+10
-x/-1=2y+10/-1
x=−2y−10
Substitute−2y−10 for x in−10x−y=−14
−10x−y=−14
−10(−2y−10)−y=−14
19y+100=−14
19y+100+−100=−14+−100
19y=−114
19y/19=-114/19
y=-6
Substitute−6 for y in x=−2y−10
x=−2y−10
x=(−2)(−6)−10
x= 2
x=2 and y=−6
Answer:i think it would most likely be c
