Answer:
b
Step-by-step explanation:
let the width be w
length=w+10
area=w(w+10)
w²+10w=255
use quadratic formular
50..........................................
The measurement of angle b is equal to 100
1. 2*0.8 = 1.6 PQ = 1.6
2. arctan(14/12) = 49.4 degrees
3. 15 * cos(70) = 5.1 feet
4. x = 30 * cos(40) = 22.9813 = 23.0 miles
y = 30 *sin(40) = 19.2836 = 19.3 miles
27 = 1 x 27, or 3 x 9. Factors of 27: 1, 3, 9, 27.
