Remember, all inside angles in a triangle add up to 180°
So:
3x+5x+7+x+2=180
Combine like terms
9x+9=180
Subtract 9 from both sides
180-9=171
9x=171
Divide by 9 on both sides
171/9=19
x=19
Plug it into all the angle measures.
Angle X: x+2, 9+2=11, Angle X=11°
Angle Y: 5x+7, 5(9)+7=52, Angle Y=52°
Angle Z: 3x, 3(9)=27, Angle Z=27°
Answer:
zero
Step-by-step explanation:
since there is no number less than 1 on the spinner, the probability of getting number less than one is zero.
Answer:
h(x) = x - 2
Step-by-step explanation:
h(x) = -2x - 4 -(-3x - 2)
-2x - 4 + 3x + 2
x - 2
Answer:
300
Step-by-step explanation:
Estimate 21
= 20
20 x 15 = 300
