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:
exact form - b = -11/5
decimal form - b = -2.2
Mixed number form - b = -2 1/5
Answer:

Step-by-step explanation:
Given :-
The sum of two numbers is 1 .
The product of the nos . is 12 .
And we need to find out the numbers. So let us take ,
First number be x
Second number be 1-x .
According to first condition :-

Hence the numbers are 4 and -3
Five-5
three-3
"the quantity five plus three" (5 + 3)
"one hundred times the quantity ..." means 100 (5 + 3)
now just solve 100(5+3)
solve the parentheses first (5+3) = 8
Now you are left with 100(8) or 100*8
when you solve your answer is 800
