Answer:
The first choice is correct
Answer:
x=35
Step-by-step explanation:
A pentagon's sum of interior angles is 540 degrees.
Now, we can set up an equation.
(4x - 57) + (3x + 15) + 4x + (2x - 3) (3x + 25) = 540
Combine similar terms
16x - 20 = 540
16x = 560
<u>x = 35</u>
Answer:
no idea just stealing the points because you reported my answer
Step-by-step explanation:
X(4x-10)^
you can write
a(b)^
where
a = x
and b = (4x-10)
so a*b have two factors a and b
b has also power = so b^ so it is means b*b*b*b*..... so b^ have always factor b
(4x-10)
4x < 10
x<10/4
x < 2.5
Answer:
111°
Step-by-step explanation:
Find Angle ACB then find angle DEC due to Isosceles triangle formation in CED.
Using the Property of Straight angel Subtract angle DEC from 180° to get 111°.
