Step-by-step explanation:
I am guessing but sorry if I am wrong
Answer:
x = 50
m∠D = 150°
m∠F = 30°
Step-by-step explanation:
- supplementary angles are two angles whose sum is 180°
∠D + ∠F = 180°
3x + x - 20 = 180
3x + x = 180 + 20
4x = 200
x = 200/4
x = 50
D = 3*50 = 150
∠D = 150°
F = 50 - 20 = 30
∠F = 30°
Step-by-step explanation:
8y+17°=6x+7° (vertical opposite angle)
6x+7=3x-29. (interior angle on same side)
3x=-36
x=-12°
B=C
-72+7=-36-29
-65=-65
Answer:
Yes
Step-by-step explanation:
X is just an unknown variable which can be substituted as another variating condition. I.E Function of x can be written as Function of a. If no other condition is present.
