Pls help...im in a rush w this math hw

1: yes, because side MQ creates two right triangles inside the equalateral one,  serving as the leg of both (reflexive property). In each right triangle, MQ would be the height.

2. (im unsure but i THINK i did it right)

1=yes

2=no

3=yes

3:The missing side would be 24.7

Step-by-step explanation:

Explanation for #3- A squared +B sqaured = C squared.

You know that one of the legs is 8 less than 42

42-8=34

34=one of the legs.

lets plug them all in: 42 squared - 34 sqaured = ?

1764-1156= 608

the square root of 608 is 24.7

so the missing side is 24.7

I hope this helps :)
