Answer:
Yes they are congruent
Step-by-step explanation:
they are congruent because they have 2 similar side lengths and 1 equal angle
Answer:
A. True
Step-by-step explanation:
Polynomials consist of at least 2 or more terms.
In this case, Binomial's bi- means "2", which allows for Binomial to fall under the category of Polynomials.

Hello from MrBillDoesMath!
Answer:
Area = 28
Perimeter = 14 + 2 sqrt(17)
Discussion:
In our case
b1 = length of EH = 3 - (-3) = 3 + 3 = 6
b2 = length of FG = 4 - (-4) = 4 + 4 = 8
h = 2- (-2) = 2 + 2 = 4
So
Area = A = (1/2)h(b1+b2) = (1/2)(4)(6 + 8) = 2(14) = 28
Perimeter = length of EH + length FG + length of EF + length of HG
= 6 + 8 + ? + ?
From the Pythagorean theorem
HG = sqrt ( 1^2+ 4^2) = sqrt(17)
Similarly
EF = sqrt(17)
So Perimeter =
6 + 8 + sqrt(17) + sqrt(17)
= 14 + 2 sqrt(17)
Thank you,

Answer:
angle A = 18°
angle B = 36 + 3(18) = 90°
angle C = 54 + 18 = 72°
Step-by-step explanation:
A triangle is a shape with 3 sides. The total angle of a triangle is 180°. This means the sum of all the angle is 180°.
Let
angle A = a
angle B = 36 + 3a
angle C = 54 + a
The sum of angle A, B and C should be equals to 180°. Therefore,
a + 36 + 3a + 54 + a = 180°
collect like terms
5a + 90 = 180
5a = 180 - 90
5a = 90
divide both sides by 5
a = 90/5
a = 18°
angle A = 18°
angle B = 36 + 3(18) = 90°
angle C = 54 + 18 = 72°
Answer:
8
Step-by-step explanation:
You just need to multiply 20 by 2/5
Or, multiply 20 by 2, then divide by 5.
20 x 2/5
40/5
8
