This diagram is a straightedge and compass construction. A is the center of one circle, and B is the center of the other. Explain how we know \bigtriangleup ABC△ABC is equilateral.

answer: 323 is how many she has ☃☃⛄❄

step-by-step explanation:

16

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
