Answer:
EFG = 50.6, LMN = 129.4
Step-by-step explanation:
ok so s supplementary angles mean, their angles will always add upto 180. for example if one angle is 100° then the other will be 80°.
to find the angles first we need to solve for x.
we know EFG + LMN = 180 because its supplementary.
that's is (3x+17) + (12x-5) = 180.
we now solve for x;
15x+12 = 180
15x = 168, x= 168/15 = 11.2
now that we know x we can put this value in the corresponding equation of EFG and LMN to find the angles.
EFG = 3x11.2 + 17 = 50.6
LMN = 12x11.2 - 5 = 129.4
Answer: 10x^2-10x
Explanation: You would distribute the 5x into the parenthesis making it 10x(to the second power) -10x
1. 5 and E, 6 and F, 7 and D, 8 and A, 9 and G
<h3>9 × 6</h3>
Because the surface area is rectangle and the area of rectangle is length × width
length = 9
width = 6.
so 9×6
