The meaning of a quadrilateral inscribed in a circle is that the angles on the opposite vertices are supplementary or in other words equals to 180 degrees.
In this exercise it is asked you to find the measure in degrees of angle A. First of all, you have to find the value of x. To do this you have to select two angles on this case angles A and C.
m<A+m<C=180 Substitute the values of angles A and C
2x+9+3x+1=180 Combine like terms
5x+10=180 Subtract in both sides by 10
5x=170 Divide in both sides by 5 to isolate x
x= 34
Now that the value of x is known, you can substitute it into the expression representing angle A.
m<A=2x+9
m<A=2(34)+9
m<A=77The measure of angle A is 77 degrees.

Answer:
Step-by-step explanation:
69 + 15h = 39h
69 = 39h - 15h
69 = 24h
69/24 = h
2.875 hrs <======
69 + 15(2.875) = 39(2.875)
69 + 43.125 = 112.125
$ 112.125 = $ 112.125 <====
I didn't round anything.
The answer is= n= 11/2 and in decimal it’s n=5.5
Explanation:
You first move the constant to the right
4n=16+6 you then calculate which will be 4n=22 and then you divide both sides
The answer is 175.45
Surface area of a cone = πrs + πr2
Volume of a cone = 1/3πr2h.
The slant of a right circle cone can be figured out using the Pythagorean Theorem if you have the height and the radius.
Answers for volume problems should always be in cubic units.
