Answer:
27.5
Step-by-step explanation:
this is the trigonometric ratio.. we are looking for d... that is the opposite... any side facing the angel is the opposite.... so the longest side of the right angle triangle is the hypotenuse........ so you are looking for the opposite and you are giving the hypotenuse.... so the easiest way to know how to find it is by using this way...... SOH CAH TOA..... the first words stand for sin cosine and tangent of angles.... we are using sin.... because it says opposite / hypotenuse... and as you can see the angle which is 39 degree we will use sin 39.....what will be sin 39=d/30m....then ull cross multiply.... d=30m* sin 39.....
d = 30m *0.963
d = 28.8
but since 27.5 is dere....
you can round up to 1 sig. f =28
The answer is 10mm, I answered this in a previous question.
The circumference of a circle -
The radius is
10 in.
5 or more add one more
4 or less could care less(aka don't change the number)
93 right and round it to the nearest hundreds
So ig 93 than you look at the tens is it more than 5 or less than 4?
It's more than 5 so you add another number on the hundreds since there is nothing on the hundred place it is 100(Answer)if it was less than 4 it would just be 0. Hope I helped
