(42) complementary angles

two angles are complementary (see # 41) the meaasure of one angle is 1 1/2 times the measure of the other. find the measure of each angle

(41) the sum of the measure of two complementary angles is 90% if one angle measure 15% more than twice the measure of its complement, find the measure of each angle.

The measure of a complement of an angle is three more than twice the measure of the angle. Find the measures of the complement.

------

angle: x

complement: 90-x

-----------------------------

Equation:

90-x = 2x+3

3x = 87

---

x = 29 


First name the variables.

Let  be the angle.

Let  be the complement.

1. By definition.

That's the first equation.

Then also,

2. 

Now you can substitute eq. 2 into eq. 1 and solve for .

.


degrees

Then from eq. 1,

degrees
