Answer: 0</h3>
=============================================
Explanation:
The original equation is in the form a+b = 1, where
a = sin(theta)
b = cos(theta)
Square both sides of a+b = 1 to get
(a+b)^2 = 1^2
a^2+2ab+b^2 = 1
(a^2+b^2)+2ab = 1
From here notice that a^2+b^2 is sin^2+cos^2 = 1, which is the pythagorean trig identity. So we go from (a^2+b^2)+2ab = 1 to 1+2ab = 1 to 2ab = 0 to ab = 0
Therefore,
sin(theta)*cos(theta) = 0
2(2x) + 2(10x + 24) = 360
use the distributive property
4x + 20x + 48 = 360
combine like terms
24x + 48 = 360
subtract 48 from both sides
24x = 312
divide both sides by 24 to isolate the variable x
x = 13
The correct answer is A. 13.
