Question

What is the area of △RST?

Enter your answer as a decimal in the box. Round only your final answer to the nearest tenth.

Answer 1

The answer to the area of a triangle RST is 26.329
We are given the sides a and b and the angle T
So, a=8, b=9 and T=47'
Now we can use the formula ab
`(sinT)/(2)`
So we place the numbers 8(9)
`(sin(47))/(2)`
Which then we get 26.329
Or as asked to the nearest tenth as 26.3

Answer 2

-------------------------------------------------------------------
Formula:
-------------------------------------------------------------------
Area of a triangle = 1/2 a b sin C

-------------------------------------------------------------------
Find Area:
-------------------------------------------------------------------
Area = 1/2 (8) (9) sin (47)
Area = 26.33 yd²

-------------------------------------------------------------------
Answer: 26.33 yd²
