114.50 if you add everything together and then subtract 67.50 you’ll get your answer
Answer:2.5%
Step-by-step explanation:
2.5% of the school has sibloings
55+45=100
100÷40=2.5
The answer is 0.0017. Do you not have a calculator?
Step-by-step explanation:
It's a question of trigonometry.
You need to remember that tangent (tan) stands for Perpendicular / Base.
So, tan P = QR / PR
By Pythagoras Theorem,
34² = 30² + x²
x² = 34² - 30²
x² = 1156 - 900
x² = 256
x = 16
Now, placing the values,
tan P = 30 / 16
tan P = 1.875
