The two unknown sides are equal to each other so then the two unknown angles are also equal.

A triangle angles add up to 180
36 + 2x = 180
2x = 180 - 36
2x = 144
unknown angles x = 72°

draw line down center of triangle to make two right triangles with side 22/2 = 11. SOH CAH TOA

cos(72) = 11/H
H = 11/cos(72)
H = 35.6

perimeter = 22 + 2(35.6)
perimeter = 93.2 cm

answer E .

Daniel [21]
These techniques for elimination are preferred for 3rd order systems and higher. They use "Row-Reduction" techniques/pivoting and many subtle math tricks to reduce a matrix to either a solvable form or perhaps provide an inverse of a matrix (A-1)of linear equation AX=b. Solving systems of linear equations (n>2) by elimination is a topic unto itself and is the preferred method. As the system of equations increases, the "condition" of a matrix becomes extremely important. Some of this may sound completely alien to you. Don't worry about these topics until Linear Algebra when systems of linear equations (Rank 'n') become larger than 2.

Answer:

531.25

Step-by-step explanation:

1)

Y = 2% x 25,000

2) Converting percent to decimal:

p = 2%/100 = 0.02

Y = 0.02 x 25,000

Y = 500

3)

25,000+500=25,500

4)

25,500/48=531.25
