19. -x-2 = 2/3x + 3
5/3 x + 3 = -2
5/3x = -5
x = -3

20. none are correct, you can double check me by plugging in the x and y values in the coordanates into the first problem none of them worked out in the first equasion so no need to test the second

21. -3 is the answer, capable of being done by using desmos

Find the area of the trapezoid using the formula using the A=1/2h(b1+b2)

pentagon [3]

Answer:

9

Step-by-step explanation:

1/2 bh (b1+b2)
Count all the squares for the base (6 squares)
Half it bc 1/2bh, which is not 3(h)
Now count the amount of squares to the top of it from the bottom (3 as well)
Now the problem is 3(3) which is 9.
So, the answer is 9

Hope this helps! Comment on it if you need more explanation!:)

The angles of an equilateral triangle are congruent. If x represents the measure of one angle of an equilateral triangle, which

dezoksy [38]

4) x + x + x = 180°

An equilateral triangle has three sides of equal length. Its interior angles are also equal. Since interior angles of a triangle should sum up to 180°, then each angle is 60°, making each angle congruent with one another.

So if x is equal to one angle and triangles have three angles then,

x + x + x = 180°

or 3x = 180°
