The answer to this is 10b = 3b. This is not possible, therefore you would have to add a slash through your equal sign for it to be a correct answer.

How do I solve #7? do i add all the angles together like a normal triangle and make it equal to 180?

kobusy [5.1K]

Answer:

126 degrees

Step-by-step explanation:

Triangle: y = 180 - (5x + 4x)

Straight angle: y = 180 - (4x + 30)

180 - (5x + 4x) = 180 - (4x + 30)

5x + 4x = 4x + 30

5x = 30

x = 6

Angle:

y = 180 - (5x + 4x)

y = 180 - 9x

y = 180 - 9(6)

y = 126

For the answer to the question above, just use similar triangles.
Here's the equations that I used.

t/h = (x + t) / r 
x + t = rt / h 
x = rt / h - t
I hope my answer helped you in your problem, Have a nice day
