Can u help me find the answer to #5 and 6​
Arlecino [84]

Answer:

5) x = 24

6) x = 48

Step-by-step explanation:

I'd be glad to help :)

For question 5, we know that 62 and the unknown angle is a straight angle, so 62+y = 180. y = 118. We also know all the angles in a triangle add up to 180, so x+(x+14)+118 = 180. Therefore, 2x+132 = 180. We now know that 2x = 48, so x = 24 for question 5.

For question 6, We know that because the line is divided up, (x+35) can be moved down a line, so (2x+1)+(x+35) = 180, so 3x+36 = 180. We now know that x = 48 for question 6

Suppose the diameter of a circle is 10. What is its area?
r-ruslan [8.4K]
Well hello again :3.  This is also quite simple.  The diameter of a circle is 2 times the radius.  So we can refit this into the equation and say that our new formula using diameter is pi(d^2/2).  Now we can say that 10/2 is 5 and 5^2 is 25.  Therefore your answer is 25pi or 78.54.
