Lily and Laura pooled their money to purchase their brother, Liam, a video game. The video came cost a total of $45. If Laura was only able to contribute LaTeX: \frac{2}{3}2 3of what Lily did, how much did Laura put towards the present? Group of answer choices

A.$18

B.$21

C.$24

D.$27

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

english maybe i can ..

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
