44u-36
Step-by-step explanation:
42u-36+2u
44u-36
Okay so you would use cos? = adjacent/hypotenuse so cos? = 31/57 so to find the angle you would do cos^-1(31/57) = ? so ? = 57.05 degrees. make sure your calculator is in degree mode
15x-6

21x/2+3. Multiply everything by 2: 30x-12=21x+6. Combine like terms: 9x=18. Get the unknown by itself: 9x/9=X. 18/9=2. X is less than or equal to 2 :)
The answer is C; 25 by 36
