Sorry, I only know 8, 9, and 10.
8. This can be anything, but my guess would be 40 - 20 = 20
9. 3, because 3 x 3 = 9.
10. 7, because 7 x 4 = 28.
Hope this helped!
Answer:
cos34°
sin56°
Step-by-step explanation:
Sin(2x+42)= sin90-(3x+13)
Sin(2x+42) = sin(90-13-3x)
Sin(2x+42) = sin(77-3x)
2x + 42 = 77-3x
5x. = 35
X = 7
If x = 7
cos(3x+13) = cos((3*7)+13)
cos(3x+13) = cos(21+13)
cos(3x+13)= cos34
And
sin(2x+42) = sin((2*7)+42)
sin(2x+42)= sin (14+42)
sin(2x+42) = sin56
If u and v are perpendicular, then their dot product is zero:

Solve for p :
