Answer:

a. X=30°

b. y=80°

solution,

a.

[tex]x + 60 = 90(sum \: of \: right \: angle) \\ or \: x = 90 - 60 \\ x = 30[/tex]

b.

[tex]y + 100 = 180(sum \: of \: angle \: in \: straight \: line) \\ or \: y = 180 - 100 \\ y = 80[/tex]

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°
