Answer:
Q 1. 8 yds Q2. 12 ft :)
Step-by-step explanation:
I got this right on my test so it should be the same.
OK we have a right angle A and we're interested in angle B.
Relative to B, AB=7 is the adjacent side and AC=17 is the opposite side so we have:
![\tan B = \dfrac{\textrm{opp}}{\textrm{adj}} = \dfrac{17}{7}](https://tex.z-dn.net/?f=%5Ctan%20B%20%3D%20%5Cdfrac%7B%5Ctextrm%7Bopp%7D%7D%7B%5Ctextrm%7Badj%7D%7D%20%3D%20%5Cdfrac%7B17%7D%7B7%7D)
![B = \arctan \frac{17}{7} \approx 67.62 ^\circ](https://tex.z-dn.net/?f=B%20%3D%20%5Carctan%20%5Cfrac%7B17%7D%7B7%7D%20%5Capprox%2067.62%20%5E%5Ccirc)
Answer: 68
(x - 5)^2 = 9
(x - 5)(x - 5) = 9
x^2 - 10x + 25 = 9
x^2 - 10x + 25 - 9 = 0
x^2 - 10x + 16 = 0
(x - 8)(x - 2) = 0
x - 8 = 0
x = 8
x - 2 = 0
x = 2
solution : x = 8 and x = 2
Answer:
x=5
Step-by-step explanation:
we can see:
20 inches= x +3x
x?
so we have
20=4x
x=20/4
x=5
