Answer:

Step-by-step explanation:

The way the triangle is laid out, BC is the hypotenuse, and AB is the side opposite <C. You hare given that the Sin<C = 1/2

If Sin<C = 1/2 then C = 30 degrees. It is part of the unit circle.

The tan (<30 degrees) = 1/sqrt(3) from the unit circle.

The cotangent of 30degrees = 1/tan(30) = sqrt(3)

cot(30) = sqrt(3) = 1.7321

Answer:

351.48cm²

Step-by-step explanation:

Heron’s Formula

Find half the perimeter (30+30+26)/2=43

It’s the square root of each side subtracted from 43, multiplied together, times 43.

√(43-30)*(43-30)*(43-26)*43=√13*13*17*43=√=123539=351.481cm²

Mademuasel [1]

Answer:

Step-by-step explanation:

∠ BSR + ∠ TSB = ∠ TSR , substitute values

2x + 17 + 5x + 15 = 102 , that is

7x + 32 = 102 ( subtract 32 from both sides )

7x = 70 ( divide both sides by 7 )

x = 10 → B
