Mhanifa can you please help? Look at the picture attached. I will mark brainliest!
kiruha [24]

Answer:

see explanation

Step-by-step explanation:

Since the marked angles are congruent, let them be x

(6)

The sum of the interior angles of a quadrilateral = 360°

Sum the angles and equate to 360

x + x + 120 + 90 = 360

2x + 210 = 360 ( subtract 210 from both sides )

2x = 150 ( divide both sides by 2 )

x = 75

Then ∠ X = ∠ Y = 75°

---------------------------------------------------------------------

(7)

The sum of the interior angles of a hexagon = 720°

Sum the angles and equate to 720

x + x + 108 + 103 + 149 + 90 = 720

2x + 450 = 720 ( subtract 450 from both sides )

2x = 270 ( divide both sides by 2 )

x = 135

Then ∠ X = ∠ Y = 135°

Gabriel has 15 5/8 pounds of clay. He will use 7/10 pound to make each bowl. After making 8 bowls he wonders how many more bowls
evablogger [386]
7/10 x 8 = 5 6/10
15 5/8 - 5 6/10 = 10 1/40
10 1/40 / 7/10 = 14 9/28
so he can make 14 more bowls and 9/28 of another bowl so you round down to 14 complete bowls.
