Answer:

See Explanation

Step-by-step explanation:

According to the Question,

  • Given That,  ∠T and ∠S are complementary & ∠S and ∠U are complementary

Thus, m∠T + m∠S = 90 ------ Equation 1

&  m∠S + m∠U = 90  ------- Equation 2

  • Now, Subtract Equation 2 From Equation 1, we get

m∠T - m∠U = 0

Thus, m∠T = m∠U

The measure of angle T is equal to angle U.(∠U≅∠T).

The mean of five numbers is 25, what is their sum?
zubka84 [21]

125 is the answer.

A mean of vie numbers is 25. If it is 25, the numbers must be 25. So, since there is 5 of 25, multiply 25 by 5. Then, the answer would be 125.

There is also another way to do it. Set-up your equation.

x/5=25.

Now flip it to make the equation a multiplication problem.

25×5=x

Once you solve the equation, you should get 125 is the answer.

x > -8cm

x < 12cm - 4cm

x < 8cm

-8cm < x < 8cm
