Answer:
366.6 mm²
Step-by-step explanation:
Step 1: find XY using the Law of sines.
Thus,

m < W = 180 - (70+43) (sum of angles in a triangle)
W = 180 - 113 = 67°
WY = 24 mm
X = 43°
XY = ?

Cross multiply:


Divide both sides by 0.68 to solve for XY


XY ≈ 32.5 mm
Step 2: find the area using the formula, ½*XY*WY*sin(Y).
Area = ½*32.5*24*sin(70)
Area = ½*32.5*24*0.94
= 32.5*12*0.94
Area = 366.6 mm² (nearest tenth)
Answer:
Yes, they are proportional
Step-by-step explanation:
First, simplify each fraction
30/80 can be simplified by dividing each number by 10
30/80
= 3/8
24/64 can be simplified by dividing each number by 8
24/64
= 3/8
So, each fraction will simplify to 3/8, meaning that they are proportional.
