Answer:

x = 12

Step-by-step explanation:

The sum of exterior angles is = 360

one of the angle is given we will need to add all three angles

128 + 8x + 11x + 4 = 360 add like terms

19x + 132 = 360 subtract 132 from both sides

19x = 268 divide both sides by 19

x = 12 replace x in required expressions to find the measure of the angles

What is the area of a rectangle with vertices (-8, -2), (-3,-2), (-3,-6), and (-8,-6)?

Gemiola [76]

Answer:

The area of the rectangle is 20 square units

Step-by-step explanation:

Through the x values of the ordered pairs, we can see that the length of the rectangle is 5

$-3-(-8)=5$

Through the y-values of the ordered pairs, we can see that the width of the rectangle is 4

$-2-(-6)=4$

The area can be found by multiplying the length and width, so this means

$(5)(4)=20$
