1. If lines r and s are parallel and t is transversal, what can you say about
a) any pair of angles that are boxed?
b) one boxed and one unboxed angle?
2. If ∆B = (2m - 20)° and ∆C = (130 - m)°, what is the value of m and the measures of ∆B and ∆C?
Pls pa sagot

Explanation: lahat ng nka box are corresponding angle at corresponding angles are congruent
2.B+C=180
(2m-20) + (130-m) = 180
m +110 = 180
-110 = -110
M= 70
B= (2m- 20)
=2(70) -20
=140-20
=120
C=130-m
=130-70
=60
