A)if x° and 60° makes a right angle, find the size of x°. [hint : x° + 60° =90°]. b)if y° and 100° make a straight
angle, find the size y°.

a. X=30°

b. y=80°

solution,

a.

b.

hope this helps..

Good luck on your assignment..

Use the hints to your advantage.

a)

x° + 60° = 90°

x = 90 - 60

x = 30°

b)

y° + 100° = 180° (straight line)

y = 180 - 100

y = 80°

c, because the american revolution was from 1765 to 1783.
