Ray KN is the angle bisector of angle JKL. Explain how you could find m angle JKN
if you know m angle JKL.

See Explanation

Step-by-step explanation:

Given

Angle: JKL

Bisector: KN

Required

How to determine JKN if JKN is known

When a line bisects an angle into two, the angle are divided into two equal parts.

In this case, JKL is bisected by KN;

The resulting angles are JKN and NKL

So:

--------- (1)

From the explanation, we can understand that JKN and NKL hold the same value.

i.e.

So, (1) becomes

Divide by 2

Take for instance; JKL =8

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
