Answer: 138
Step-by-step explanation:
1.38 * 100 = 138
Answer: B) 122 and 58
Supplementary angles add to 180 degrees. In other words, they form a straight angle or a straight line when you combine them together (make sure they don't overlap and that there isn't any gap between them).
Choice B is the only pair of angles where they add to 180 since 122+58 = 180. The values in choice A and choice D add to 90; the values in choice C adds to 270.
Note: complementary angles add to 90 degrees. One way to remember "supplementary" vs "complementary" is to think "S for straight, C for corner". By "corner", I mean a 90 degree corner.
Answer:
x = -2/5
Step-by-step explanation:
x + 3 - 2x = 4x + 5
Combine like terms
-x + 3 = 4x + 5
Subtract 4x from both sides
-5x + 3 = 5
Subtract 3 from both sides
-5x = 2
Divide both sides by -5
x = -2/5
Inverse means the opposite. it's a bit confusing..I believe it's either C or D.
