Answer:
So since the 2 angles are congruent they will be the same.
Step-by-step explanation:
So since the 2 angles are congruent they will be the same. So for example, if I have a triangle and angle 60 and two congruent angles it will be 60 + 2x =180. I congruent angle will be x then 2 of that is 2x. Angles in a triangle always sum up to 180.
Answer:b
Step-by-step explanation:
Answer:
Find the base, and then the height of this rhombus;
Base: 7 square units
Height: 7 square units
Multiply your base by the height to get the area;
Because the formula for the area of a rhombus is, A = BH
So,
A = 7(7)
A(area) = <u>49 square units</u>.

Answer:
Step-by-step explanation:
The easiest way to determine the answer to your question is to evaluate the
discriminant
For a quadratic in the form:
y
=
a
x
2
