Triangle def is congruent to right triangle ghi with a right angle at vertex h. if the slope of de is –2, what must be true?

the slope of hi is 1/2.

the slope of ef is 1/2.

the slope of gh is –2.

the slope of df is –2.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

i think the answer is b x = 1, y = 35/2
