4-3=1
1+8=9
The answer is 9
You should definitely ask your parents or teacher. Also, never give up :)
Trust me just keep trying your best and don't tell yourself that you can't do it :)
tan(3θ + 17) = cot(θ + 7)
(3θ + 17) + (θ + 7) = 90
(3θ + θ) + (17 + 7) = 90
4θ + 24 = 90
- 24 - 24
4θ = 66
4 4
θ = 16.5
4a + 3 = 15
- 3
4a = 12
÷ 4
a = 3
I hope this helps!
