To find the angle of this roof pitch we look up the arc tangent of

6. No, the conclusions wrong because 20 out of 50 peoples favourite is drawing which means 20/50 which equals 0.4 times 100 which is 40% not 60%
7. Yes, the conclusion is right because 5/50 is equal to 0.1 times 100 which is 10%
412 + 162 + 347 = 921. Because it is closer to 900 than 1,000, the answer is 900.
