Answer: 41.1
Step-by-step explanation:
To find the value of x, we need to use SOH-CAH-TOA. SOH-CAH-TOA is since, cosine, and tangent. The O, A, H stands for opposite, adjacent, and hypotenuse respectively.
Looking at the figure, we see 47°. The labelled angles are adjacent and the hypotenuse. Therefore, we use CAH or cosine.
[multiply both sides by x]
[divide both sides by cos(47)]

When we plug that into a calculator, we get x=41.1.

Answer : 12cm^2
Step-by-step explanation:
A = bh/2
A = 8 * 3 /2
A = 24/2
A = 12 cm^2
The complex number would turn into 2(cos -pi+i sin -pi)
