Given: ∠A is a straight angle. ∠B is a straight angle.
We need to Prove: ∠A≅∠B.
We know straight angles are of measure 180°.
So, ∠A and <B both would be of 180°.
It is given that ∠A and ∠B are straight angles. This means that <u>both angles are of 180°</u> because of the <u>the definition of straight angles</u>. Using <u>the definition of equality</u>, m∠A=m∠B . Finally, ∠A≅∠B by <u>definition of congruent. </u>
Answer:
8 ft
Step-by-step explanation:
The area of a paralellagram is b*h. Since we know the base, 15, we can plug this into an equation.
15(h) = 120.
Divide by 15 on both sides to get you 8.
Answer:
65 miles
Step-by-step explanation:
There are two simultaneous equations
. Remeber that v=d/t, 1hour = 60 minutes.
1. 40 = (d+15)/(t+0.5)
2. 50 = d/t
solving: d= 25 miles and t=0.5 hours.
The distance traveled is:
D=d+d+15
D=65 miles
Answer:
I believe its D , to increase the acceleration of a object you have to increase the force preferably ,the mass kind of slows it down because of the weight .
But d is the most legit answer so :p

Put 5 instead of x
g(5)=5^2-4=21
