Answer 1

Answer:Step-by-step explanation:

sum of equilateral triangle=90degree

now,3x+2y=12x+4y/3+3x+3+3/2y-3/2=90degree

3x+2y+4x+4y+3x+3y=90degree

10x+9y=90(1)

9y=90-10x

y=90-10x/9

y=10-10x(3)

put the value of (y) in equation(1)

10x+9y=90

10x+9(10-10x)=90

10x+90-90x=90

10x-x=90

9x=90

x=10units

hope it is understandable plese mark me as brainliest
