Step-by-step explanation:
Given: y // z Prove: measure of angle 5 plus measure of angle 2 plus measure of angle 6 equals 180 degrees
Answer:
b = 7
Step-by-step explanation:
Since the triangle is right use the tangent ratio to solve for b
and the exact value
tan30° = , thus
tan30° = = and
= ( cross- multiply )
b = 7
It's 169.6mm in total so that closer to H
170mm
