Answer:
39 units
<h3>
Step-by-step explanation:</h3>
Since two side lengths and a right angle are given, we can use pythogoras theorem to determine the missing side (c) of the triangle. It should be noted that pythgoras theorem can only be used if the triangle is a right triangle.
<u>Pythogoras theorem formula:</u>
Substitute the legs of the triangle and the hyptenuse
Simplify both sides of the equation
Take square root both sides
![\implies \sqrt[2]{1521 } = \sqrt[2]{c^{2} }](https://tex.z-dn.net/?f=%5Cimplies%20%5Csqrt%5B2%5D%7B1521%20%7D%20%20%3D%20%5Csqrt%5B2%5D%7Bc%5E%7B2%7D%20%7D)
Solve for "c" by simplifying the roots
![\implies \sqrt[2]{39 \times 39 } = \sqrt[2]{c \times c }](https://tex.z-dn.net/?f=%5Cimplies%20%5Csqrt%5B2%5D%7B39%20%5Ctimes%2039%20%7D%20%20%3D%20%5Csqrt%5B2%5D%7Bc%20%5Ctimes%20c%20%7D)
Thus, the measure of the missing side length (c) is 39 units.
Answer:
5, 13, 10, 8
Step-by-step explanation:
hello, so for this question keep in mind the triangle inequality theorem which states- a side must be smaller than the sum of the other two sides.
go through each of the choices.
a. 5+7=12 12>9
b.2+7=9 9>9 this cant be the answer since 9 is equal to nine, not greater than,
c. 13+7=20 20>9
d.10+7=17 17>9
e.8+7=15 15>9
f.22+7=29 29>9 although 29 is greater than 9, we also have to keep in mind that the other 2 sides must also be greater than the other side. so try 7+9= 16. 16 isnt greater than 22 so it can’t be one of the answers.
hope this helped :)
Answer:
1800 is the original cost
Step-by-step explanation:
cost + 11% cost = 1998
Factor out the cost
cost *( 1+11%) = 1998
cost ( 1.11) = 1998
Divide each side by 1.11
cost = 1998/1.11
cost =1800
