Answer:
Step-by-step explanation:
m∠AOB+m∠BOC=180°
m∠AOB=8x+51°
m∠BOC=6x-25°
~
m∠AOB:-
Therefore, m∠AOB=139°
You are moving in the path of a parabola.
The conic section is parabolic - the street is the directrix and the mailbox is the focus.
Answer:
27 feet squared
Step-by-step explanation:
the formula for the area of a triangle is b(h)/2 so u just plug in the numbers into the formula from the question. we know that the base is 6ft long and the height is 9ft long.
A = b(h)/2
A = 6(9)/2
A = 27
therefore the area of the sail is 27 feet squared.
Answer: 20 degrees
Step-by-step explanation:
- You add both angle for them to equal 180
- You solve for x
- 3x-10=20; 6x+100=120
Answer:
13, 15, 17
Step-by-step explanation:
If we let the smallest of these odd integers be "x"
then the next one is "x + 2"
and next one is "x + 4"
We can write an equation from the word problem:
x + x+2 + x + 4 = 2x + 19
let's find x, the smallest, and then find the other 2:
The next one is 15, and next one is 17
The three consecutive odd integers are 13, 15, 17
