Answer 1

Answer:

The answers for this are as followed:

Area = 906.12058  (Rounded to the nearest tenth = 906.1)

Perimeter = 138.94608  (Rounded to the nearest tenth = 138.9)

Semiperimeter = 69.47304 (Rounded to the nearest tenth = 69.5)

Step-by-step explanation:

This is an Acute Scalene Triangle, with the side and angle measurements being:

Side A = 49

Side B = 40.17851  (Rounded = 40.2)

Side C = 49.76757  (Rounded = 49. 8)

------

Angle ∠A = 65° = 1.13446 rad

Angle ∠B = 48° = 0.83776 rad = 4/15π

Angle ∠C = 67° = 1.16937 rad

------

∠C = 180° - A - B = 1.16937 rad = 67°

b = a·sin(B)/sin(A) = 40.17851

c = a·sin(C)/sin(A) = 49.76757

In order to find the area, just use the equation: $\frac{ab x sin(C)}{2}$
