There are values of t so that cos t=5/4 O A True O B. False​

I think its false but im not 100 percent sure i hope this helps

Step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

you need to show us the graph.
