Question

Somebody please help me with this problem !? Angle addition with relationship between angles.

Answer 1

m2 = 25 °

Explanation:

69 = m1 + m2

but m1 is just (m2 + 19) so

69 = m2 + 19 + m2 = 2× m2 + 19

subtract 19 from both sides

50 = 2×m2

divide by 2

25 = m2

Answer 2

25°

Explanation:

whole angle = 69°

m<1 is 19 more than m <2 then

(69 - 19) ÷ 2 = m<2

m <2 = 25
