Radius = 15
side = 6.215

a^2 = 15^2 - 6.215^2
a = 13.65

Area = a × p
Area = 13.65 × 99.44
Area = 1357.356

Answer:

The second one is d. 13

Step-by-step explanation:

Add what you know first. 110+57= 167. Then, subtract what the angle is all together with the answer from what you know. 180-167= 13. X= 13. I'm bad at explaining so I hope that was clear.

Find x<br> A) 4<br> B) 4 root 2<br> C) 4 root 3<br> D) 8 root 3

This triangle is a 30-60-90 triangle, which you can just find by solving for the unknown angle in the triangle, making it a 30-60-90 triangle.

You'll need to memorize the side lengths for these triangles, but the side opposite from the hypotenuse (x in this case), will be half the length of the hypotenuse.

Meaning that 2x=8

So x=4

Hope this helps.

頑張って!
