An angle measures 3.2° less than the measure of its complementary angle. What is the measure of each angle?
cupoosta [38]

Answer:

<h2>        43.4° and 46.6°</h2>

Step-by-step explanation:

x   - measure of angle

x + 3.2°   - measure of its complementary angle

Complementary angles adds to 90°

x + x + 3.2° = 90°

2x = 90° - 3.2°

2x = 86.8°

 x = 86.8°÷2

 x = 43.4°

x+3.2° = 43.4° + 3.2° = 46.6°

A printer can print 40 pages in 1.6 minutes
Rzqust [24]
Given:
40 pages in 1.6 minutes

40 / 1.6 = 25 pages per minute

25 x 5 minutes = 125 pages

40 / 1.6 = x / 5
40*5 = 1.6x
200 = 1.6x
200/1.6 = x 
125 = x  pages

25 : 1 = 150 : x
25x = 150
x = 150/25
x = 6 minutes
