The length of EF in the right triangle

Mathematics
2 answers:
LiRa [457]3 years ago

In order to find the sides of a right triangle, you can use the pythagorean theorem. (a^2 + b^2 = c^2)

The pythagorean theorem basically means that the square of two sides is equal to the square of the hypotenuse (the longest side of a triangle)

In this case, we already have 'a' and 'c', but not 'b'.

12^2 + b^2 = 19^2

Mutliply everything:

144 + b^2 = 361

Isolate b into one side by subtracting both sides by 144:

b^2 = 217

Square root both sides in order to completely isolate b:

b = \sqrt{217}

The answer is Option F

Good luck!

Answer:

F.

\sqrt{217}

Step-by-step explanation:

Use the Pythagorean Theorem, which is a^2 + b^2 = c^2.

c represents the hypotenuse, or the longest side of the right triangle. c in this case would be 19.

Side a can be represented as 12 since it is the other side that has a given value.

Substitute in the values to get the equation: (12)^2 + b^2 = (19)^2

12 squared is 144 and 19 squared is 361. To figure out what b^2 is subtract 361 - 144 to isolate the variable. We will be left with b^2 = 217.

In order to find what b is, find the square root of 217, which is Choice F.

Giving the following information:

Money spent= $59

Proportion of savings= 25% = 0.25

<u>To calculate the total savings before shopping, we need to use the following formula:</u>

Savings= money spent / proportion of savings

Savings= 59 / 0.25

Savings= $236

zvonat [6]

Answer:

8 times larger

The ratio of the side lengths of a quadrilateral is 3:2:6:7, and its perimeter is 126 meters. What is the length of the shortest
scoundrel [369]

since the lengths of all those four sides are in a 3:2:6:7 ratio, and the whole perimeter is 126, what we do is, simply divide the whole by (3+2+6+7) and distribute accordingly.


\bf \stackrel{3\cdot \frac{126}{3+2+6+7}}{3}~~:~~\stackrel{2\cdot \frac{126}{3+2+6+7}}{2}~~:~~\stackrel{6\cdot \frac{126}{3+2+6+7}}{6}~~:~~\stackrel{7\cdot \frac{126}{3+2+6+7}}{7} \\\\\\ 3\cdot \cfrac{126}{18}~~:~~2\cdot \cfrac{126}{18}~~:~~6\cdot \cfrac{126}{18}~~:~~7\cdot \cfrac{126}{18} \\\\\\ 21~~:~~\stackrel{shortest}{14}~~:~~42~~:~~49
