Answer:
4 flights of stairs in 5 minutes
Step-by-step explanation:
8/10 times 5
So this is a right triangle so you can use sin, cosine, or tangent. for A, you have the sides opposite and hypotenuse, which means you use sin*
sin(A) = opposite / hypotenuse
sin(A) = 56 / 75
arcsin(56/75) = A
A= about 48.3
so to the nearest degree, your answer is 48
*soh cah toa (if you dont know what that is, i can explain it)
Do the brackets first as it says in BIDMAS
5/6 or 83% (roughly, since probability is never exact).
(hope this helps!)
The answer would be x + x + 2 = 72. Combine like terms so that 2x + 2 = 72. 2x = 70 and x = 35.
