The answer is the forth one , Y-8+2⩽-2+2
Answer:
90°
Step-by-step explanation:
EG is a straight line
EG = EHD + DHG
DHG is a 90 degree angle
180 = EHD +90
Subtract 90 from each side
180-90= EHD +90-90
90 = EHD
The arc has the same measure as the angle since it is from the center
arc ED = 90
These 2 angles are "vertical angles." Thus, angle 1 = angle 4.
Therefore, 6x+1 = 8x-17. Solving for x, 2x = 18 and x = 9 (answer)
