Triangle mrn is created when an equilateral triangle is folded in half. what is the value of y? a. 2√3 units b. 4 units c. 4√3 units d. 8 units

we know that

If Triangle MRN is created when an equilateral triangle is folded in half

then

so

Applying the Pythagorean Theorem in triangle MRN

we have

substitute

solve for y

therefore

the answer is the option C

The correct option is C.

Step-by-step explanation:

It is given that triangle MRN is created when an equilateral triangle is folded in half.

It means original equilateral is triangle MNO and NR is a perpendicular bisector. The side length of the triangle is

Since NR is a perpendicular bisector, therefore

Using Pythagoras property in triangle MNR,

Therefore option C is correct.

d) 48

step-by-step explanation:

16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304,320,336

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
