How do i put this in a calculator? x-7 — =-2 4

You cant but you can solve it in a caculator

Step-by-step explanation:

first you have to add 7 at -2

then you multiply 5 with 4 you get 20 remember 20 is the = 20 ok

and that is your awnser

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
