Answer:

75 degrees.

Step-by-step explanation:

All interior angles of a triangle add up to 180.

So we can set up an equation: 65+40+x=180

105+x=180

x=180-105

x=75

H 24 inches The volume of a cylinder can be found by using the formula v Bh. Which expression can be used to determine B, the ar
Lelechka [254]
The volume a cylinder is v=(area of base)h and since the area of the base is πr², you can write the equation a v=πr²h.  Since the problem wants us to find what be is in the equation of a cylinder as v=Bh, we know that B=πr².  The problem gave us the diameter of the circle so we no the radius is going to be the diameter (24) divided by 2 which equals 12.  therefore B=12²π.

I hope this helps.

Which is the best estimate of 90/7 divided y 1 3/4? 2 6 12 24
Vilka [71]
The answer to this question would be: 6
In this question, you are asked to estimate 90/7 divided by (1 + 3/4). You can convert the 1 3/4 into :
1 +3/4=
4/4 + 3/4= 7/4
Then, the calculation would be:
(90/7) / (7/4)= (90*4)/ (7*7)= 7.347

The distance from 7.347 to 6 would be -1.347. It was much shorter than the distance to 12 which is 4.7. The closest answer would be 6
