Answer: The two triangles are similar because the angles are congruent.
Step-by-step explanation: If you add the given measures of the angles given, then subtract from 180, the remainder is equal to the measure of the angle given for the other triangle.
180 - (103 + 22) = 55
180 - (22 + 55) = 103
So both triangles have the same angle measurements.
This should be -4x^2-4x+4.

Answer:
(d) $775.50
Step-by-step explanation:
The parallelogram on the left has an area of ...
A = bh = (4 yd)(2 yd) = 8 yd²
The rectangle in the middle has an area of ...
A = lw = (6 yd)(4 yd) = 24 yd²
The triangle on the right has an area of ...
A = 1/2bh = 1/2(1 yd)(2 yd) = 1 yd²
The total area of the carpet is ...
(8 + 24 + 1) yd² = 33 yd²
__
At $23.50 per square yard, the cost is ...
($23.50/yd²)(33 yd²) = $775.50 . . . . . matches the last choice
The side of the triangle is 13 inches
Side of square. 6 inches
X= side of square
4x+15 =3(x+7)
4x+15=3x+21
x=6
6+7= 13
Perím square 6x4= 24
Perim triangle 13x3=39
39-24=15
