Examine the diagram.

Triangle A B C. Side A C is parallel to a line. The line is at angle B. The angles formed by the line are 70 degrees, B, 30 degrees.

Find the interior angles of the triangle.

Which kind of angle pair is angle A and the angle marked 70°?

What is the measurement of each angle?

m∠A = °
m∠B = °
m∠C = °

believe it or not anna is correct good job anna give me a fist bump there u go gal

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
