Answer:
D) 67.4°
Step-by-step explanation:
by observation, and noting that triangle PQR is a right triangle
sin R = opposite length / hypotenuse
in our case, the hypotenuse is PR = 13 and the length opposite form R is QP = 12
hence
sin R = opposite length / hypotenuse
sin R = 12/13
R = sin⁻¹ (12/13) = 67.4⁰
Answer:
4
Step-by-step explanation:
7x = x² - 8
=> x² - 7x - 8 = 0
use quadratic formula:
a = 1, b = -7, c = -8
x = 
<em>(pls ignore the "A" I don't know why it's showing up)</em>
=> x = 
=> x = 
=> x = 
= 4 or 
= -5 <em>(the answer is only 4 since it's asking for the positive solution)</em>
