Question

In this figure please see pictures

Answer 1

h= 75

look where a is. c is perpendicular to it, making it 105 as well.
b is supplementary to it, so u have to figure its angle to understand what h is.
now im guessing you know to subtract 105 from 180 (bc these angles are supplementary) which is 75.
like I was saying, looking at a and c, you notice e and g are the same as them. what is supplementary to e? h. (e being 105 makes h 75)
I hope I helped u understand how this works bestie

Answer 2

∠ h = 75°

Explanation:

∠ e = ∠ a = 105° ( corresponding angles )

∠ h and ∠ e are adjacent angles and sum to 180°

∠ h + 105° = 180° ( subtract 105° from both sides )

∠ h = 75°
