Find the area of the triangle. round your answer to the nearest tenth. triangle abc line ab =15 yd, line ac = 15 yd, ∠a= 48° a. 112.5 yd2 b. 167.2 yd2 c. 124.9 yd2 d. 83.6 yd2

A = 83.6 yd² ⇒ answer (d)

Step-by-step explanation:

∵ AB = 15 , AC = 15 and m∠A = 48°

∵ Area of the Δ by using sin Rule

∴ A = 1/2 × S1 × S2 × sin including angle between two sides

∴ A = 1/2 × 15 × 15 × sin48 = 83.6 yd² ⇒ answer (d)

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

can you put the picture up?
