Sin r = 20/29
SOHCAHTOA
R:
(O) opposite - 20
(A) adjacent - 21
(H) hypotenuse - 29
X2+13x-48
(x-3)(x+16)
X=3, X=-16
3 and -16 are the Zeros
- linear pairs are supplementary, meaning they add up to 180°
5x + 9 + 3x + 11 = 180
8x + 20 = 180
8x = 160
x = 20
- now plug in.
angle 1: 5(20) + 9 = 100 + 9 = 109°
angle 2: 3(20) + 11 = 60 + 11 = 71°
Answer:
$35
Step-by-step explanation:
This is actually pretty simple!
All you have to do is plug 5 in place of x and solve.
Y=5(5)+10
Y=25+10
Y=35
She raises $35 if she walks 5 kilometers.
