305-35=270 (SA of 3 triangular faces)
270/3=90 (area of one face)
A=.5BH
90=.5(9)H
90=4.5H
H=20 in
I would say 20
I’m not so totally sure but I believe it’s that because of the ratios, CB:CE is 3:6, and then CA:CT would probably be 10:20. does that make sense?
sorry if i’m incorrect
Can I see the question ?
There isn’t a question ..???
Step-by-step explanation:
We can see that:-

and

are in Opposite manner , so, we will add three angles together. These are as follows:-

You, know why I did 180°, that is because these all angles form a straight line and we know that straight lines have angle of 180°.
Continuing with the equation:-






Now, in order to find y we need the value of 3x+6. And when we will find it, it will be Vertically Opposite hence the answer will directly be placed to find y.
