Answer:
x = 50
m∠D = 150°
m∠F = 30°
Step-by-step explanation:
- supplementary angles are two angles whose sum is 180°
∠D + ∠F = 180°
3x + x - 20 = 180
3x + x = 180 + 20
4x = 200
x = 200/4
x = 50
D = 3*50 = 150
∠D = 150°
F = 50 - 20 = 30
∠F = 30°
D. Because there are three odds and three evens meaning there is only going to be 1/2 chance you roll and odd
If I'm understanding the question correctly, this is how I would estimate the sum.
I would round each number to the nearest tens place.
33 would be rounded down to 30.
89 would be rounded up to 90.
Then I would do 90+30.
Answer:
Step-by-step explanation:
All this takes is the use of the power rule, which, for integrals, says that
∫ = .
With this in mind, we can integrate:
∫
= .
We can also check our answer by differentiating our answer:
so we are correct!
hope this helped!
