Answer:

18° and 72°

Step-by-step explanation:

The angle measures are unknown, so they will be represented with the variable, x.  Since, one angle is 4 times the other, this will be represented with 4x.

To find complementary angles, they are added together and equal 90. So let's create an equation.

x + 4x = 90

Now solve for x.

5x = 90

5x/5 = 90/5

x = 18

One angle is 18°.

Now find the second angle.

4x

plugin 18 for x and multiply

4(18) = 72

Solve the inequality -2x is less than or equal to 3x + 1 is less than or equal to 10
KatRina [158]
-2x < = 3x + 1 < = 10

split them
-2x < = 3x + 1         3x + 1 < = 10
-2x - 3x < = 1          3x < = 10 - 1
-5x < = 1                 3x < = 9
x > = -1/5                 x < = 3

solution is : -1/5 < = x < = 3 <==
