What is z?
a. 88
b. 92
c. 95
d. 124

z = 92

Step-by-step explanation:

First we find the value of y using angle sum property( sum of the angles of a triangle is 180)

Then we use linear pair property( y and x are linear pairs. all linear pairs sum up to 180)

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'.

the answer is 8.64
