Answer:
110
Step-by-step explanation:
Using pythagorean theorm
c^2 = a^2 + b^22
610^2 = 600^2 + b^2
372100 = 360000 + b^2
b^2 = 12100
b = 110
Answer:
55
Step-by-step explanation:
took the test
Answer:
40
Step-by-step explanation:
Let n represent the integer. Then the increase can be written as ...
n + (-12) = 28
We can add 12 to both sides of this equation:
n + (-12) + (+12) = 28 +12
n + 0 = 40 . . . . . . -12 and 12 total to zero; 28 and 12 total to 40.
n = 40
The integer is 40.
B is 50 and A is all of them?
Answer:
x = 40
Step-by-step explanation:
Using similarity theorem, we have the following:

Solve for x

Cross multiply


Subtract 24x from each side


Divide both sides by -15
40 = x
x = 40
