What is the area of the shape?

30

Step-by-step explanation:

7 * 3 = 21

3 * 3 = 9 which covers for both triangles

each triangle is half of a square. so each triangle is 4.5 sq. units

add 21 with 9

21 + 9 = 30

42 square units.

Step-by-step explanation:

First, find the area of the rectangle, which is base*height or 7*3=21.

Next, find the area of the two triangles, each has an area of 1/2*b*h, since there are two of them, their collective area is b*h, or 7*3=21.

21+21=42 square units.

(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
