Hope this helps, so sorry if I am wrong!
Answer:
100°
Step-by-step explanation:
I assume the image is the one attached below.
The shapes are quadrilaterals, so their interior angles add up to 360°. Three of those angles are 86°, 41°, and 133°. So the fourth angle is:
x + 86° + 41° + 133° = 360°
x = 100°
Answer:
w = 4 1/2
l = 6
Step-by-step explanation:
w = width
2w-3 = length
A = lw
27 = w(2w-3)
27 = 2w² - 3w
subtract 27 from each side:
2w² - 3w - 27 = 0
factor:
(2w-9)(w+3) = 0
solve each for 'w':
w = 9/2
w = -3 (This answer can be discounted because a length cannot be negative)
width = 9/2
length = 2(9/2) - 3 which is 6
Answer:
Angle ABC = 58
_________________
These two angles are opposite but meet at the same vertex. This means that they are equal to each other. To solve the equation below, isolate the variable and you have your answer!
3x - 14 = 2x + 10
-2x -2x
x - 14 = 10
+14 +14
x = 24
Angle ABC
3(24) - 14 = ?
72 - 14 = 58
