Find the measures of the angles labeled in the figure on the right.

M

Step-by-step explanation:

since we have at F a 90 degree angle, b is simply the difference between 90 and 33 degrees

b = 90 - 33 = 57 degrees.

and since all angles in a triangle must sum up to 180 degrees, this applies also to HFG. and we know 2 angles : H = 54 degrees, b = 57 degrees

a = 180 - 54 - 57 = 69 degrees

e is simply the counterpart of the 90 degree angle at F, as these 2 angles must sum up to 180 degrees again.

so, e = 180 - 90 = 90 degrees.

c is the complementary angle to 54, as for a pair of angles at a line intersection, these 2 angles must again sin up to 180 degrees

c = 180 - 54 = 126 degrees

and d is the third angle of EFG, where we know 2 angles, and again, the sum of all angles must be 180.

d = 180 - 90 - 69 = 21 degrees

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
