Find the mausure of 1

88

Step-by-step explanation:

Every triangle has a measure of 180, so if we know two of the angles we can find the last one easily. To find angle 1, we first must find angle 2. 2 must be equal to 42 because it is vertical to the other angle that is equal to 42 degrees. Then to find angle 1 do the operation 180-(50+42). This equals 88, which is the measure of angle 1.

the two may have that, even a breakdown is probably offered

a)(x-2)^2+(y-1)^2=9
