Answer:
10
Step-by-step explanation:
10+3 = 13
13 x 7 = 91
CosB= 7/25
tanB= 24/7
sinB= 24/25
For problems like this you can move the y's on the bottem up top by fliping the sign of the exponent (in this case 7 to -7) and MULTIPLYING it with EVERYTHING on top, then because of properties of multplication you can add the exponents to combine them into one term (in this case add 3 and -7 to get -4)

If any of this does not make sense let me know and ill try to clarify better
