Question

Help needed with this triangle - finding measure of sides - trig. question PLEASE!! Fan and medal!

Answer 1

Y is obviously 7 as well.

Answer 2

You don't even need trig to do this one. You can just use the Pythagorean Theorem:

a^2 + b^2 = c^2

where "a" and "b" are each "7".

If you have to use trig, you can use the sine function where the sine of an angle is the ratio of the opposite side over the hypotenuse.

Answer 3

Ohh ok. The leson today was covering trig, so I just figured u had to use it.

So, 7 squared the 7 7 squared
49 plus 49 = 98.
So the bottom is 98?

Answer 4

98 is c^2, so you have to take the square root of that. Hint:

98 = 7 x 7 x 2

Answer 5

Ohhh!!! So... 9.89....
