To find the area, we need the height of the triangle first. We already have the base.
Let's find the height (BA)
tan = opposite / adjacent
tan 35 = BA / 12
BA = 12 * tan35
BA = 12 * 0.7002079283708176
BA = 8.402
Area of the triangle = 12*BA/2 = 6*BA = 50.412 square units
The answer to your questions is c
There are 2.5 grams of niacin contained in the bottle.
First you have to find how many milligrams are in the bottle.
So you multiply 125 by 20 since there are 125 tablets and 20 milligrams in each one.
125*20=2500
So there are 2500 milligrams in the bottle. Then you have to convert it into grams. To do that you divide the mass by 1000.
2500/1000=2.5
So there are 2.5 grams in the bottle.
Answer:
r = +8 or -8
Step-by-step explanation:
This is because when you square -8 or +8, you will get 64
A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.
So basically for your expression:
