Answer:
<h3 /><h3>The number is 162</h3>
Step-by-step explanation:
Let the number be<u> x</u>
5/9 of the number is 90
Which is
5/9 of x = 90
5/9 × x = 90
5/9x = 90
Multiply through by 9
That's
5x = 810
Divide both sides by 5
5x/5 = 810/5
x = 162
Therefore the number is 162
Hope this helps you
A)she is not right.because if the remaining peice is the hypotenuse of the triangle, the answer will be around 27.8 if the hypotenuse is 22 then the missing angle is 13.96
b)yes it will work
if you double the measurements of the two sides of a right triangle the other one will be double, too(you can get help from Pythagoras theorem )
c)yes it is possible. if we can double the sides of a right triangle it means that we add measurements to the triangle.
for example:a triangle with sides of 3,4,5
if we add 6,8,10
it will be 9,12,15
hope I could help
Answer:
The side lengths that are the legs are 6 and 12 because the hypotenuse is the largest side length of a triangle (since there are three side lengths shown).
Answer: q=7

Answer:
Step-by-step explanation:
There is no such thing as the inverse Law of Cosines. You CAN use the law to find a missing angle, which is found by finding the inverse cos of a ratio. For example, if you have all 3 sides of a non-right triangle and you are looking for the measure of an angle, you would do all the required math, and in the end you would have that cos(x) = some fraction. Take the inverse cos on your calculator of this fraction and get the angle value.
In other words, the Law of cosines can be used to find both a missing side OR a missing angle.
