Given the right triangle ABC with right angle B, angle A is twice the size of angle C. If the measure of side AB is 7 units, what is the measure of side AC?

AC= 14 units

Step-by-step explanation:

Given

--- right-angled

Required

Find AC

The question is illustrated using the attached triangle

The angles in a triangle are:

Substitute and

Collect like terms

To find AC, we make use of the sine of angle C:

--- i.e. opposite/hypotenuse

So:

Make AC the subject

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

the answer is c)8
