Answer:
x = 6
Step-by-step explanation:
Verticle angles are formed when two lines intersect. The angles opposite each other are congruent, those angles are called vertical angles.
Using this knowledge, one can say;
3x + 2= 20
Use inverse oeprations to solve for "x"
3x + 2 = 20
-2 -2
3x = 18
/3 /3
x = 6
The answer is 70cm for the height because you would multiply 50cm x 35cm and you would get 1750. Then you would divide that by 122,500 and you will get the height
