Answer:
Step-by-step explanation:
-3x=16+5
-3x=21
x=21/-3
x= -7
Answer:
x= 110°
Step-by-step explanation:
if you continue drawing the top purple line you will have a triangle with three angles
70° ; is given
180-140= 40°; is the same angle as the supplement angle of 140° (complementary angles are congruent)
180-70-40 = 70°; because sum of angles in a triangle is 180°
So angle x= 180 -70 = 110 because are a linear pair
What? I have an idea of what your saying but i'm not positive. Can you explain better please?
