Step-by-step explanation:
If you would like to calculate (a + 1) * (a + 2) - (a + 1) * (a - 2) - a - 1, you can do this using the following steps:
(a + 1) * (a + 2) - (a + 1) * (a - 2) - a - 1 = a^2 + 2 * a + 1 * a + 2 - (a^2 - 2 * a + 1 * a - 2) - a - 1 = a^2 + 3 * a + 2 - a^2 + 2 * a - 1 * a + 2 - a - 1 = 3 * a + 3
The correct result would be 3 * a + 3.
A° = 1/2 (90) = 45°
b° = 1/2[360 - (110 + 90)]
b° = 1/2(160)
b° = 80°
a° + b° = 45° + 80° = 135°
Answer
135°
By the Pythagorean Theorem, the lengths of the sides of a triangle satisfy 
if the triangle is a right triangle (in which case the angle between sides a and b is the right angle).
