Answer:
m∠ACD=124°
Step-by-step explanation:
∠mACD +m∠DCB=180°
2x+8+x-2=180
3x+6=180
3x=174
x=58
m∠ACD=2x+8=2*58+8=124
m∠ACD=124°
Let's break it up into 2 figures, the rectangle on the right with dimensions 3 x 10, and the rectangle on the left with dimensions 8 x 6.
A = 3 x 10
A = 8 x 6
A = 30
A = 48
The sum of these two, 78, will represent the area of the total figure.
Factorization of sin²θ + sin²θ cos²θ gives us; 2sin²θ - sin⁴θ
<h3>How to simplify Trigonometric Functions?</h3>
We want to simplify;
sin²θ + sin²θ cos²θ
Let us factorize out sin²θ to get;
sin²θ(1 + cos²θ)
Now, we know that cos²θ = 1 - sin²θ
Thus;
sin²θ(1 + cos²θ) = sin²θ(1 + 1 - sin²θ)
⇒ sin²θ(2 - sin²θ)
⇒ 2sin²θ - sin⁴θ
