Answer:

125

Step-by-step explanation:

A is an inscribed angle. The central angle is 90, so angle A is 45.

110/2 = 55

180 - 45 - 55 = 80

Angle B is 80.

80 + 45 = 125

Please help me solve this LCM

hodyreva [135]

Note that

$x^2 - y^2 = (x - y) (x + y)$

and

$x^2 + 2xy + y^2 = (x + y)^2$

Then their LCM is $\boxed{x + y}$ .
