Answer:
The measures of the angles are 50° and 130°
Step-by-step explanation:
Let
x ----> the measure of one angle
y ----> the measure of the other angle
we know that
If two angles form a linear pair , then their sum is equal to 180 degrees
-----> equation A
----> equation B
substitute equation B in equation A
solve for y
Find the value of x
The measures of the angles are 50° and 130°
The area of the trapezoid, to the nearest whole number is: D. 8 units²
<h3>What is the Area of a Trapezoid?</h3>Area of trapezoid = 1/2(a + b)h, where:
Using the coordinates of the trapezoid, (0,0), (1,3), (4,3), (2,0), the points have been plotted on a coordinate plane as shown in the image attached below, and we have the following dimensions of the trapezoid:
Area of the trapezoid = 1/2(a + b)h = 1/2(3 + 2)3
Area of the trapezoid = 7.5 ≈ 8 units²
