Answer:
m<BAC= 110 degrees
Step-by-step explanation:
Since the outside angle m<BCD is 130 degrees the inside angle m<BCA would be 50 degrees. At this point you should know that inside angles of a triangle add up to 180 degrees so add the two angles that you know then subtract from 180 degrees. 50+20= 70 degrees and 180-70= 110 degrees.
Answer:
3
Step-by-step explanation:
(20a - 1) ÷ b
a = 2
b = 13
(20(2) - 1) ÷ 13
(40-1)÷13
39÷ 13
= 3
