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.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

y + 11 = (1/4)(x + 16)
