Angle S and angle T are congruent. Angle S measures 2x + 5 and angle T measures 5x – 25. What is the measure of angle S?

Since the two angles are congruent, then 2x+5 and 5x-25 must be equal.

2x+5=5x-25
-3x+5=-25
-3x=-30
x=10

Now we can plug in x=10 into the expression for angle S:
2x+5 --> 2(10)+5 = 25

The measure of angle S is 25 degrees.

X is 10 so 2(10)+5 is 25 degrees for angle S

Given:

Perimeter of cube = 84 cm

Find:

Total surface area of cube

Computation:

Perimeter of cube = 12 x side

84 = 12 x side

Side = 7 cm

Total surface area of cube = 6(a)²

Total surface area of cube = 6(7)²

Total surface area of cube = 294 cm²

For #1
city A's mean would be 10.5, then you would divide it by the number of numbers there is which is 5,So 10.5/5 is 2.1

city B's mean would be 11.6 then you would divide it by the number of numbers there is which is 5, So 11.6/5 is 2.32.

thats all I have don't know how to do #3 sorry
