What is the value of y? a(3y+70) b(25) c(5x)

now, let's take a peek at the legs AB and AC, they both have a tickmark, meaning AB = AC, so we have an isosceles triangle with twin sides.

and twin sides will make twin angles at the "base", namely 25 = 5x.

since we know then a triangle has a total of 180° for interior angles, and we also know that ∡B = ∡C = 25°, so 25+25 = 50, so whatever the ∡A is, 180 - 50 = 130°.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
