Answer:
155°
Step-by-step explanation:
The sum four angles is 360° so:
60°+45°+100°+x=360°
x = 360°-100°-45°-60°=155°
3x+x= 180°(straight angle)
4x= 180°
x= 180/4
x= 45°
Answer:
Step-by-step explanation:
if we have a right triangle,
one angle=90
180-90=90
let x be one angle, and y another angle
the other is 2x+30
x+2x+30=90
3x=60
x=20
y=70
The answe is the answer is 8
