Alex787 [66]

Answer:

The emergency medical technician made $739.12 per week

Step-by-step explanation:

Given that:

Per hour pay = $19.71

One month earning of emergency medical technician = $3326.06

Weeks in the following month = 4.5

For per week income, we will divide the monthly salary by number of weeks in the month.

Per week income = $\frac{3326.06}{4.5}$

In the above givem figures all the angles can be found by complementary pair of angles.

What do you mean by complementary pair of angles?

There are basically two types of pair of angles i.e. Supplementary & Complementary.
Supplementary means that sum of two angles is 180°. It is also known as linear pair of angles. It is always formed on straight line.
Complementary pair of angle is that when sum of both angles is 90°. It is formed when a right angle is bisected.

<h3>Fun Fact: All angles of a square and rectangle are of 90°.</h3>

∠A+45°=90°

∠A+45°=90° ∠A=90°-45°

∠A+45°=90° ∠A=90°-45° ∠A=45°

Hence, ∠A is 45°

 ∠B+65°=90°

 ∠B=90°-65°

 ∠B=25°

Hence, ∠B is 25°

 ∠C+52°=90°

 ∠C=90°-52°

 ∠C=38°

Hence, ∠C is 38°

 ∠D+40°+34°=90°

 ∠D+74°=90°

 ∠D=90°-74°

 ∠D=16°

Hence, ∠D is 16°
