Answer:
the angles are 80 degrees and 40 degrees
Step-by-step explanation:
The sum of two opposite interior angles equal to the exterior opposite angle.
so;
4x + 2x = 120
x = 120 / 6
x = 20
4x = 80
2x = 40
Answer:
y=4
Step-by-step explanation:
The triangle on the right is a 30-60-90 triangle
The ratio of sides in a 30-60-90 triangle is 1:√3:2
y:x:8
SO y will be 4 because 8/y=2/1
That's already in standard form
