Answer:

x = 15

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180 , that is

2x + 5 + 25 + 8x = 180 , simplify

10x + 30 = 180 ( subtract 30 from both sides )

10x = 150 ( divide both sides by 10 )

x = 15

Answer:

x=15º

Step-by-step explanation:

180=25+8x+5+2x

180=30+10x

180-30=10x

150=10x

15=x

The perimeter of a rectangle garden is 54yd. One side has a length of 15 yd. Find the area of the garden.

Lelechka [254]

Answer:

=》Area = 180 sq.yd

Step-by-step explanation:

perimeter = 2l + 2b

where, we have l = 15

so (2×15) + 2b = 54
30 + 2b = 54
2b = 24
b = 12

now, Area = l × b = 12 × 15 = 180 sq.yd
