1. 96

2. x= 10.909 (10.91 (rounded))

Step-by-step explanation:

1. You can break the figure into 3 parts, a triangle and 2 rectangles

For the triangle, we have this information:

height is 3

length is 8

angle is 90 (right angle)

area = 0.5 * 3 * 8 * sin(90)

area is 12

For the two rectangles, just multiply the length * width

5 * 4= 20

8 * 8= 64

Then add them ALL together

12 + 20 + 64 = 96

2. x = √(12^2 - 52^2)

x= 10.09

(10.91(rounded))

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'.
