Answer:
15° , 45°, 120°
Step-by-step explanation:
sum the parts of the ratio, 1 + 3 + 8 = 12 parts
the sum of the 3 angles in a triangle = 180° , then
180° ÷ 12 = 15° ← value of 1 part of the ratio, then
3 parts = 3 × 15° = 45°
8 parts = 8 × 15° = 120°
the 3 angles are 15° , 45° , 120°
Y intercept: when x = 0
Plug in x = 0
F(0) = -0^2 + 10(0) - 22
F(0) = 0 - 22
The y intercept is (0,-22)
Answer:
21 = -10m - 3
Add 3 to both sides:
24 = -10m
Divide by -10 on both sides:
-2.4 = m
Answer:
the ratio is 2 : 4.7
Step-by-step explanation:
3 times 2.35 equals 7, and 2 times 2.35 equals 4.7
