<u><em>Answer:</em></u>x = 7
<u><em>Explanation:</em></u><u>We are given that:</u>
l = 7x - 7
m = 4x + 14
<u>We want to have:</u>
l = m
<u>Therefore, we will simply equate the two equations and solve for x as follows:</u>
7x - 7 = 4x + 14
7x - 7 - 4x = 4x + 14 - 4x
3x - 7 = 14
3x - 7 + 7 = 14 + 7
3x = 21
x =

x = 7
Hope this helps :)
IK its an obtuse angleeee if that helps
2 km... Since 1.8 is 2(.9), you do the same for the base of the smaller triangle (just multiply by two)
1. -1
2. 1/2
not sure:
3. 7? —> 7x 1/7x=7x1= 7
4. 1/11?
