Solve for x on each of these questions please!
IgorLugansk [536]

Answer:

1. x = 10

2. x = 4

Step-by-step explanation:

I use the angle ABC method:

AB² + AC² = BC²

6² + 8² = x²

x = 10

AB² + AC² = BC²

3² + x² = 5²

x = 4

Can someone with knowledge see what I did wrong on number 4<br>also see if number 3 is right​
Yakvenalex [24]

Answer:

#4.  m=0;

#3.  m = \frac{-1}{2}

Step-by-step explanation:

It seems right.

#4.  

Maybe your teacher wants you to write m=0; because when a fraction has a numerator equal to zero then the fraction is zero.

#3.

Maybe your teachers want you to simplify the fraction and write m = \frac{-1}{2}
