Is that the whole question? It does not specify, so that means there is a 50/50 chance for either.
Answer:
D=100(opposites angles are equal)
A=C=80 (adj angles are supplementry)
Step-by-step explanation:
To find the angle of vertex E,we need to first find the sum of interior polygons to determine x:

In this case,the equation would be:
(7-2)×180°
=5×180°
=900°
We can then find the value of x:
(4)6x+(2)2x+8x=900°
24x+4x+8x=900°
36x=900°
x=25°
The interior angle of vertex E:
6x=6(25)=150°
Therefore,the interior angle of vertex E is 150°.
Hope it helps!
3 and what?
if it is 3 and 5 than the answer would be 15
Answer:
9
Step-by-step explanation:
m = j^2 -7p
18 = j^2 -7(9)
18 = j^2 - 63
81 = j^2
√81 = √j^2
9 = j
