A, B & C form the vertices of a triangle. CAB = 90°, ABC = 60° and AB = 8.6.

Calculate the length of BC rounded to 3 SF.

BC =

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.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

dont trust me im no expert these losers made me fail a test bro this sucks
