The diagram shows a right-angled triangle. 9 cm
to
15 cm
Find the size of angle x.
Give your answer correct to 1 decimal place.

x ≈ 31.0°

Step-by-step explanation:

From the right triangle given in the picture,

By applying tangent rule,

tan(x) =

tan(x) =

x =

x =

x = 30.96

x ≈ 31.0°

Therefore, measure of angle x is 30.0°

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
