C. Since ST is a diameter, the angles that make it up sum to 180. So SRV + TRV = 180. So TRV = 180 - 53 = 127

that's the solution ^

the answer is: 847.98 m^2

Rewrite 72 as 6^2 •2

Factor 36 out of 72

**Step-by-step explanation:**

**What is a triangle?**

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted.

Basic rule:

A triangle must be tri-sided, means it must have three sides which is **only possible if the sum of the smaller two sides is greater than the third side. Otherwise, a triangle is not physically possible.**

A- 2+3 = 5 hence not a triangle.

**B- 3+7 > 9 hence a triangle.**

C- 4+5 < 9.5 hence not a triangle.

D- 5+6 < 12 hence not a triangle.
