Answer:
21 units^2
Step-by-step explanation:
Dimensions of rectangle are 3 by 6 units; therefore the area is 18 units^2.
Dimensions of triangle: base is 3 and height is 2; therefore the area of this triangle is (1/2)(base)(height) = (1/2)(3)(2) = 3 units^2
The total area of this figure is (18 + 3) units^2, or 21 units^2

Answer:
- b = 757.7 m
- A = 17.2°
- C = 14.3°
Step-by-step explanation:
From the law of cosines, you can find the length of side b to be ...
b = √(a² +c² -2ac·cos(B))
b = √(184041 +128164 -307164cos(148.5°)) ≈ √574105.36
b ≈ 757.7
__
From the law of sines, you can find the measure of angle C to be ...
C = arcsin(c/b·sin(B))
C ≈ arcsin(358/757.7·sin(148.5°)) ≈ arcsin(0.246872)
C ≈ 14.3°
A = 180° -148.5° -14.3°
A = 17.2°
