Assuming the triangle is a right triangle, the answer would be 78 degrees.

Since the angles of a triangle must equal 180 degrees, 180-12-90=78

A number is divided by 5, then added to 18. The answer is 9 less than 62. What is the original number?
Scorpion4ik [409]

Answer: The original number is 175

Step-by-step explanation:

The number will be represent by x .

The number is being divided by 5  so we can represent by the expression x/5.

After than is being added to 18  so we will add 18 to the expression.

x/5 + 18 .

It has to equal to 9 less than 62 and 9 less than 62 is the same as the expression  62 -9.

Whole equation will be   x/5 + 18 = 62 - 9  

\frac{x}{5} + 18 = 62 - 9     Combine like terms on the right side

x/5 + 18 = 53        Subtract 18 from both sides

      -18     -18

x/5 = 35     Multiply both side by 5.

x = 175

This means the original number is 175.
