Step-by-step explanation:
trust me i used to this all the time
well you didn't show problem 11 but here is a pretty photo of Port orford Oregon
x=25
25 degree angle is the same as x
the answer is 6
2x + 9 = 21
2x = 21 - 9
2x = 12
x = 6
4
B = (6,5) C = (6,9)
√(x2 - x1)² + (y2 - y1)²
√(6 - 6)² + (9 - 5)²
√(0)² + (4)²
√16
= 4
