∠CEB and ∠AED are vertical angles, which means they must be equal to each other. Make them = x in an equation. The angles form a quadrilateral, so the sum of the interior angles must equal 360°.
77 + 77 + x + x = 360
Combine like terms.
154 + 2x = 360
Subtract 154 from both sides.
2x = 206
Divide both sides by 2.
x = 103
∠CEB is greater than 90°, so it must be an obtuse angle.
645+x >| 800 (the inequality)
800-645= 155
So, Micah needs to deposit at least $155.
(Btw >| is the greater than or equal to sign.)
Answer:
86
Step-by-step explanation:
Given, x = 5
length of a rectangle = 6x-4 = 6 * 5 - 4 = 30-4 = 26
width of a rectangle = 3x + 2 = 3 * 5 + 2 = 15 + 2 = 17
Now , finding the perimeter of the rectangle :
Perimeter of a rectangle = 2 ( length + width )
= 2 ( 26 + 17 )
= 2 * 43
= 86
Hope I helped!
