73 and the angle to solve for add to 180 because they are supplementary.
180 - 73 = 107.
5x + 2 = 107.
5x = 105.
5x/5 = 105/5
x = 21
Answer:
7
Step-by-step explanation:
Answer:
Question 1: they are vertically opposite angles
Question 2:they are supplementary angles
Question 3:they are vertically opposite angles
Question 4:they are complementary angles
Step-by-step explanation:
Question 1:
a° and b° are vertically opposite angles so they are equal
Question 2:
a° and b° are supplementary angles,since their sum is equal to 180°
Question 3:
a° and b° are vertically opposite angles so they are equal
Question 4:
a and b are complementary angles,their sum is equal to 90°
Answer:
would be 4cm x 4 cm = 16 sq.cm. 6 surfaces of the cube would be 6 x 16 = 96 sq.cm. By definition, a cube has congruent sides. So, each side has an area A = s^2.
