Answer 1

Answer:

b=1399.43

Step-by-step explanation:

We know our A side (length CH) is 3960

First we have to find our c side or length CE

Add 3960 and the altitude of 240 which equals 4200

then use the Pythagorean Theorem of A squared + B squared = C squared

if you plug that in its

3,960 squared + B squared = 4200 squared

If you calculate that its

15,681,600 + b squared = 17,640,000

then you want to isolate the variable

youll want to subtract 15, 681,600 from both sides of the = sign

this gives you b squared = 1,958,400

then youll have to find the square root of both

the square root of B squared is B

the square root of 1,958,400 is 1399.43

so B = 1399.43
