Answer:
both statement have valid conclusions.
Step-by-step explanation:
A rhombus is a parallelogram with all sides equal.
A parallelogram has opposite angles congruent.
Therefore
both statements have valid conclusions.
Due to the Triangle Angle Sum Theorem, we know that the sum of the interior angles of a triangle equals 180 degrees, therefore,
180 = m<1 + m<2 + m<3
180 - m<3 = m<1 + m<2
But, we also know that m<4 + m<3 = 180 degrees.
180 = m<3 + m<4
180 - m<3 = m<4
Both m<4 and m<1 + m<2 equals 180 - m<3
m<4 = m<1 + m<2
Answer:
-8
Step-by-step explanation:
you add 5 to -7 to get -2
7 x -1 is -7
so x = -1
8 x -1 = -8
6.28 because pi x diameter = circumference.
( diameter = half of a circle)
