Question

a 32" flat screen television measure 32 inches across its diagonal. the diagonal makes a 35° angle with the bottom of the television. Select all equations that can be used to solve for the height, of the television.cos35°=h/32sin35°=h/32tan35°=h/35cos55°=h/32sin55°=h/32tan55°=h/32

Answer 1

Since it's a right triangle, we can apply the trigonometric functions:

Sin a = opposite side / hypotenuse

Sin 35 = h/32

The top angle is 55, since:

35+90+b = 180

b= 180-90-35

b= 55

We can also apply:

Cos b = Adjacent / hypotenuse

Cos 55 = h/32
