The answer for this question is 80
Answer:
The distance around a circle is called perimeter uwu! ^^
Answer:
Option C. cos70°
Step-by-step explanation:
we know that
If two angles are complementary, then the sine of one angle is equal to the cosine of the other angle and the cosine of one angle is equal to the sine of the other angle
Remember that
Tow angles are complementary , if the sum of their angles is equal to 90 degrees
so
If A+B=90°
then
sin(A)=cos(B)
cos(A)=sin(B)
In this problem we have
A=20°
B=90°-20°=70°
therefore
sin(20°)=cos(70°)
cos(20°)=sin(70°)
£840 - 100%
100%-5%=95%
840*95%:100% = 798 (£) - <span>the number sought</span>
When adding or subtracting fractions, there is one big rule: make sure the denominators are the same first!
As long as the denominators (the numbers on the bottom of the fraction) are the same, you can get an answer by adding the numerators (the numbers on top) and keeping the denominator the same.
********Here's an example********
2/3 + 3/3
First, make sure the denominators are the same. Since the number on the bottom of each fraction is the same, namely 3, we can proceed without worry.
Now add the numerators. The numbers on top are 2 and 3. 2 + 3 = 5.
The final answer is 5/3. We added together the numerators to get the top number, and kept the denominator the same for the bottom number.
***************************************
Try adding 3/4 and 4/4 together on your own now before you look ahead.
To get the answer, let's follow the process.
Make sure the denominators match. They do, so we can proceed.
Add the numerators. 3 + 4 = 7.
Keep the denominator the same. The denominator is 4.
Your answer is 7/4!

Keep on working! you got this!
