The diagram shows a right-angled triangle. 9 cm
23°

What is the value of h?
Give your answer correct to 1 decimal place.

h ≈ 21.2 cm

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan23° = = ( multiply both sides by h )

h × tan23° = 9 ( divide both sides by tan23° )

h = ≈ 21.2 cm ( to 1 dec. place )

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
