Question

Help please! ASAP!

Answer 1

If you drop a perpendicular line from point B to line b, you will have 2 right angle triangles. Now you can find out the angle and point C, and using sin, cos or tan functions, can you find the lengths?

Answer 2

No that's why I need help

Answer 3

Sorry for the bad drawing but best way to explain. Now start by finding out angle at point me. You already know the other 2 angles in the main triangle. What would be angle at point C?

Answer 4

22 right?

Answer 5

Yes, right. Now we need to find the length of line x using the line AB and sin function. Can you try to do that?

Answer 6

sin function?

Answer 7

Trigonometry: sin(43) = x/6. Rings a bell?

Answer 8

x = 6sin(43)

Answer 9

yes, so what is the value of x?

Answer 10

4.091.......

Answer 11

Now you have x, can you find length of a with the same logic and angle C?

Answer 12

Is one of the answers C?

Answer 13

sin22 = x/a.
For b you will have to add the 2 parts of b falling in each of the 2 right triangles b1 and b2

cos 22 = b1/a
cos 43 = b2/6
b= b1+b2
