If you are given with all the tree sides of the triangle, you may solve for all the angles through the Law of Cosines,
c² = a² + b² - 2ab(cos C)
where angle C is the angle opposite the side c. You may use the same equation to get the values of the remaining angle. Additionally, if you already have one known angle, you can solve for the rest of the angles by Law of Sines,
a / sin A = b / sin B = c / sin C

Answer:
75%
Step-by-step explanation:
If Mitchell took a math exam and got 63 out of 84 questions correct, that would turn into the fraction: 63/84
In order to convert this to a decimal, you divide 84 by 63 (since every fraction is a division problem), and get 0.75.
When you change decimals into percents, you move the decimal point two times to the right. So, that would be 75.
Then you add the percent symbol and you're done!
I hope that helped :)
Answer:
7 - x meters
Step-by-step explanation:
This is a difference of squares. The formula for difference of squares is
a^2-b^2 = (a-b)(a+b)
So plug the numbers we know into this formula.
Area = lw
49 - x^2 = (a-b)(7+x)
49 - x^2 = (7-x)(7+x)
<u>The length is 7 - x meters.</u>
Can you give the answer choices? that would help a lot more to find the answer they are looking for
