Answer:
a. 58
b. 35
Step-by-step explanation:
a. Given,
sinθ = cos 32
We know that cos x = sin (90 - x)
⇒ sin θ = sin (90 - 32)
⇒ sin θ = sin 58
⇒ θ = 58
Thus, the value of θ would be 58.
b. Given,
cosθ = sin(θ+20),
sin (90 - θ) = sin (θ + 20)
⇒ 90 - θ = θ + 20
⇒ 90 - 20 = θ + θ
⇒ 70 = 2θ
⇒ θ = 35
Thus, the value of θ would be 35.

Step-by-step explanation:
12.45
a dilation with a scale factor of 4, is multiplication by 4 each side, so we need the measure of the side CD and then multiply by 4 to find C'D'
we can notice tht length of CD, is 3 squares,multiplying by 4 the new length is 3x4= 1 2 squares
Answer:
<h2>x = 2</h2>
Step-by-step explanation:
3 - x + 1 = 2 <em>combine like terms</em>
-x + (3 + 1) = 2
-x + 4 = 2 <em>subtract 4 from both sides</em>
-x +4 - 4 = 2 - 4
-x = -2 <em>change the signs</em>
x = 2
