If m<3=105, what is the m<21 that will prove that lines P and R are parallel. please help

75°

have: m∠3 = m∠11 = m∠22 = 105°

but m∠22 + m∠21 = 180°

=> m∠21 = 180° - 105° = 75°

Step-by-step explanation:

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
