Which equation shows a correct relationship of trigonometric functions?

Try it on a calculator.

x + y = 90

if x = 30 and y = 60

Step-by-step explanation:

From the given right triangle.

This implies that;

Because the two angles are complementary.

We divide both sides by to obtain;

We simplify to get;

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
