Question

Help me with this one ​

Answer 1

125

Explanation:

We are given that <1=70. Using that, we know that <5 also equals 70 because of the definition of vertical angles, we then can find <2 also by subtracting 70 from 180 and dividing it by 2 to get 55. <4=<2 and <6=<5, so using substitution we can get m<CDH=125

Answer 2

<CDH = 110°

Explanation:

Given <1 = 70°

Because BF ║ CD so <1 = <3 = 70° (corresponding angles are equal)

<CDH = 180° - <3

<CDH = 180° - 70°

<CDH = 110°
