What is this angle ?

Mathematics
1 answer:
Lelu [443]3 years ago
6 0

Answer: Angles 1 and 3 are adjacent to angle 140. (because they are next to each other)

Angles 1 and 2, 1 and 140, 140 and 3, and 3 and 2 are supplementary (because together they add up to 180 degrees)

Angles 140 and 2 and 1 and 3 are vertical angles because they are across from each other.

This may be a little confusing, so don't be afraid to ask for clarification, but great luck!

All of the following are equivalent except<br> A. 5 is to 3<br> B. 45/27<br> C. 15/5<br> D. 7.5:4.5
Eduardwww [97]
I haven’t done this before but I’m sure it’s C. 15/5

5 is equal to 3.

45/27 is also equal to 5/3 (Divided both 45 and 27 by 9)

7.5:4.5 is also equal to 5:3 (Divided both 7.5 and 4.5 by 1.5)

15/5 is not equal because if you simplify it, it would become 3:1 (Divided both 15 and 5 by 5).

Anastasy [175]

Answer: \boxed{\ 28.26}

My step-by-step explanation:

  1. <u><em>We would use the formula πr2 (pi x radius x radius) </em></u>

<em>     </em><u><em>2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2</em></u>

  • <u><em> And so we find:  6mm÷2=3mm </em></u>

   3. So now that we have our radius, we can just plug the numbers into the formula.  So this would be:

  • <u><em>πr2= 3.14 x 3 x 3= 28.26mm2</em></u>

<u><em /></u>

<u><em /></u>

Hope this helps you!
