Answer:
x = 9
Step-by-step explanation:
-2x + 3 = -15
-2x = -18
x = 9
Perpendicular lines and intersecting lines are the same because they both describe 2 lines that cross one another...
They are different because perpendicular lines cross one another in a specific way. The intersection of perpendicular lines forms 90 degree angles, while intersecting lines just describes 2 lines crossing. It could be at any angle.
Additive inverse property
A = c
b = 180 - a
d = 90
a = 180 - (90 +22.6) = 67.4
x = 5 as the ratio of lengths of the small triangle to big triangle is 1:2
therefore if the big triangle has a length 10, then the small one must be 5
