Step-by-step explanation:
angle HIJ=107°
angle IDJ=31°
now,
angle HIJ+angle JID=180°{ being straight angle}
107+angle JID=180°
angle JID=180°-107=73°
again,
angle JID+angleIDJ+angleDJI=180°{ sum of angle of triangle}
73°+31°+angleDJI=180°
angle DJI=180°-1104°=76°
hence,
angleAJF=angleDJI{ vertically opposite angle}
x=76°
hope it helps.
Answer:
160
Step-by-step explanation:
Answer:y=44°
Step-by-step explanation:
Sin y =cos [90°-y]
It is Given that sin y =cos (y+2°)
Cos[90°-y]=Cos(y+2°)
90°-y=y+2°
88°=2y
y=44°
