Given triangle is a right angle triangle so we are allowed to use trigonometric formulas.
We want to find Hypotenuse using angle A and base 7 cm
so right choice is to use cosine





Hence value of side AB is approx 7.72 cm.
A ratio is used to describe how two or more quantities are related.
For example, we might say that a fruit drink calls for sugar crystals to be mixed with water in a ratio of 2:6. This means that for every 2 scoops sugar crystals, there will need to be 6 ounces of water. If there were 200 scoops of sugar crystals, there would need to be 600 ounces of water.

Answer:</h2>
<u>You can write it as |0 - x| < 6</u>
<h2>
Step-by-step explanation:</h2>
Suppose we have a number line and you are moving towards left side so we get negative numbers. The same logic applies here. You are moving to left side from 0 for 4 steps. So you can write it as
|0 - x| < 6 where x is your desired number
For A it is 6240 / 20% for B it is 6240 x 15%
Answer:

Step-by-step explanation:
recall for a line whose equation is
y = mx + b,
the slope of this line is m
the slope of a line that is perpendicular to this line is -
in this case,
m = -
hence -
=
