The answer is the number that 't' must be in order for the equation
to be a true statement.
Here's how to find it:
Write t + 8 = 15
Then subtract 8 from each side: <em> t = 7</em>
Answer:
x = -35
Step-by-step explanation:
The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
x + 55° + 55° = 180°
x = 70°
The appropriate choice is the 2nd one:
70°
2 because it's the highest exponent in the expression
