What is the area of the composite figure? Enter your answer in the box.

cm2
An isosceles triangle on top of a rectangle. The height of the rectangle is 10 centimeters and the base of the rectangle is 5 centimeters. The triangle on top has the same base length. The entire figure from the bottom of the rectangle to the top of the triangle is 18 centimeters high.

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
