Answer 1

Answer:

all sides of a equilateral triangle are equal

all sides of a equilateral triangle are equal2x + 7 = x + y - 9

all sides of a equilateral triangle are equal2x + 7 = x + y - 9x-y = -9-7

all sides of a equilateral triangle are equal2x + 7 = x + y - 9x-y = -9-7x-y = -16

all sides of a equilateral triangle are equal2x + 7 = x + y - 9x-y = -9-7x-y = -16x-y +16 = 0

all sides of a equilateral triangle are equal2x + 7 = x + y - 9x-y = -9-7x-y = -16x-y +16 = 0so y+5 = x-y+16 = 0

all sides of a equilateral triangle are equal2x + 7 = x + y - 9x-y = -9-7x-y = -16x-y +16 = 0so y+5 = x-y+16 = 0so y = -5

all sides of a equilateral triangle are equal2x + 7 = x + y - 9x-y = -9-7x-y = -16x-y +16 = 0so y+5 = x-y+16 = 0so y = -5so x+5+16 = 0

all sides of a equilateral triangle are equal2x + 7 = x + y - 9x-y = -9-7x-y = -16x-y +16 = 0so y+5 = x-y+16 = 0so y = -5so x+5+16 = 0x = -21

all sides of a equilateral triangle are equal2x + 7 = x + y - 9x-y = -9-7x-y = -16x-y +16 = 0so y+5 = x-y+16 = 0so y = -5so x+5+16 = 0x = -21so 2x+7 = -35

all sides of a equilateral triangle are equal2x + 7 = x + y - 9x-y = -9-7x-y = -16x-y +16 = 0so y+5 = x-y+16 = 0so y = -5so x+5+16 = 0x = -21so 2x+7 = -35x+y-9 = -21-5-9

all sides of a equilateral triangle are equal2x + 7 = x + y - 9x-y = -9-7x-y = -16x-y +16 = 0so y+5 = x-y+16 = 0so y = -5so x+5+16 = 0x = -21so 2x+7 = -35x+y-9 = -21-5-9= -35

Answer 2

Question:-

The figure shows an equilateral triangle with its

sides as indicated. Find the length of each side of

13.

the triangle.

(2x - 7) cm

(x + y - 9) cm

13

(y + 5) cm

${\blue{\underline{\underline{\bold{Answer:-}}}}}$

As we know that :-

all sides of a equilateral triangle are equal

2x + 7 = x + y - 9

x-y = -9-7

x-y = -16

x-y +16 = 0

so y+5 = x-y+16 = 0

so y = -5

so x+5+16 = 0

x = -21

so 2x+7 = -35

x+y-9 = -21-5-9

= -35

hence your answer is -35

hope it helps you.....
