Answer: 134
Step-by-step explanation:
(3 x a x 4 x b)-c = (3 x 4 x 4 x 3)-10
= (12 x 12) - 10
= 144 - 10
= 134
We have t+8=5 or t+8=-5
So t1 = -3 and t2 = -13
Answer:
m∠1 = 110° and m∠2 = 70°
m∠1 = 110° since vertical angles
To find m∠2, m∠1 and m∠2 must add to 180°
m∠1 + m∠2 = 180°
110° + m∠2 = 180°
m∠2 = 70°
