Answer:
6.1
Step-by-step explanation:
area =leanth x breath.
if one side=4.7,
then, missing length=area/given side
= 28.67/4.7
=6.1

Answer:
BC = 17.2.
Step-by-step explanation:
Since CAB = 90º, this is a right triangle.
The triangle format is given below:
C
A B
We have that AB = 8.6, and angle B measures 60º.
Length of BC:
BC is the hypotenyse.
Side AB is adjacent to angle B = 60º.
In a right triangle, angle , it's adjacent side with length s and the hypotenuse h are related by the cosine of the angle, that is:
In this question, we have an angle of 60º, with has cosine 0.5. We also have that side AB = s = 8.6, and the hypotenuse h is side BC. So
BC = 17.2.
Answer:
500 times
Step-by-step explanation:
They breathe 20 times per minute for 25 minutes
20(times per minute) x 25(minutes) = 500
