Step-by-step explanation:

hope this helps :)

-22

Step-by-step explanation:

-10 and -16 are a distance of two marks away

-16 and the blue dot are also a distance of two marks away

so what is the distance measure between -10 and -16?

-10- (-16)= 6

therefore

-16- (6) = -22

where are the choices?

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
