A. An angle and its supplement equals 180∘ . So subtract 55∘ from 180∘ to get the supplemental angle.
B. The supplement of 170 degrees is 180-170 = 10 degrees. The complement of 55 is 90 - 55.
sorry i don't know the number to C, but i hope i helped a little <3
30m2 because the formula is base times height.I hope this helps
Answer:
.75
Step-by-step explanation:
Answer:
y = - 2(x - 1)² + 18
Step-by-step explanation:
- 2x² + 4x + 16 ← factor out - 2 from the first 2 terms
= - 2(x² - 2x) + 16
using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² - 2x
= - 2(x² + 2(- 1)x + 1 - 1) + 16
= - 2(x - 1)² + 2 + 16
= - 2(x - 1)² + 18 ← in vertex form
