Answer:
21square feet
Step-by-step explanation:
Count the whole squares first.
if each square is one square foot then 18 whole squares will be 18×1= 18 square feet
add halves (aproximate halves) together. (3 in total)
Therefore A= 18 +3
= 21 square feet
Answer:
not a solution
Step-by-step explanation:
Substitute p = - 2 into the left side of the equation and if equal to the right side then it is a solution.
7(- 2) - 5 = - 14 - 5 = - 19 ≠ 20
Then p = - 2 is not a solution of the equation
Answer:
it depends
Step-by-step explanation:
If 17 is the hypotenuse
if you are looking for the hypotenuse
Answer:
cos(C)
Step-by-step explanation:
Recall that the sine ratio is opposite over hypotenuse.
Also the cosine ratio is adjacent over hypotenuse.
The tangent ratio does not come close because it doesn't involve the Hypotenuse.
Answer:
18.4 cm
Step-by-step explanation:
For this problem, you would use <em>Pythagorean Theorem </em>or a^2+b^2=c^2. Don't forget that the c in the formula is always your hypotenuse or the longest side of the triangle. The a and the b are always the legs of the triangle. (It doesn't matter which leg is which letter) The hypotenuse is also always across from the 90 degree angle. <u>Picture the 90 degree angle as an arrow pointing to the hypotenuse.</u> In this case, the hypotenuse (or c) is 20.7 cm. Now all you have to do is plug and chug! I hope this helps you and thanks for asking your question!!
