I need help with this question

h = 16°

Step-by-step explanation:

The total angle of a straight line = 180°.

So we can say that 151° + x = 180°

180° - 151° = x

x = 29°

total angles of a triangle = 180°

∴ 118 + 29 + 2h + 1 = 180

⇒ 148° + 2h = 180°

⇒ 2h = 180° - 148°

⇒2h = 32°

⇒h = 32° ÷ 2

⇒ h = 16°

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

the answer to the expression is 83
