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

IRISSAK [1]

Answer:

See below for answers and explanations

Step-by-step explanation:

4! = 4*3*2*1 = 24

0! = 1

2! + 3! = 2*1 + 3*2*1 = 2 + 6 = 8

3! * 4! = 3*2*1 * 4*3*2*1 = 6 * 24 = 144

10! / 7! = 10*9*8*7*6*5*4*3*2*1 / 7*6*5*4*3*2*1 = 10*9*8 / 1 = 720
