Given 6, 8, and 11 as the three sides of a triangle, classify it as one of the following acute, right or obtuse. Please help and thank you
9514 1404 393
Answer:
obtuse
Step-by-step explanation:
You may remember that side lengths of 3, 4, 5 make a right triangle. Doubling those lengths to 6, 8, 10 will still give a right triangle.
The given triangle has a longest side (11) longer than would be appropriate for a right triangle (10), so the largest angle is larger than 90°.
The triangle is obtuse.
__
Comparison of a triangle to a right triangle with two sides the same is one of several ways the triangle can be classified. You can use the Law of Cosines to find the largest angle, or you can use a triangle solver (as we have below).
In case you don't recall that 3-4-5 makes a right triangle, you can use the Pythagorean theorem to find the longest side of a right triangle with the given shorter sides:
hypotenuse = √(6² +8²) = √100 = 10
Your long side is longer, so your largest angle is larger than 90°.
Law of Cosines:
angle = arccos((6² +8² -11²)/(2·6·8)) = arccos(-21/96) ≈ 102.6°

Write an equation where the variable is divided by a number, and a solution is -4/5
Answer:
x/-5
Step-by-step explanation:
Just divide by 5 and the denominator will be 5 meaning x would have to be 4.
Make sure your 5 is negative so the whole equation also ends up negative. x/-5=-4/5
Negative ten is no less than two times a number plus forteen

how do you convert 7/6 into a mixed number or how do you covert fractions into a number in general.
Answer:
1 1/6
Step-by-step explanation:
You can convert 7/6 into a mixed number by subtracting 1 from the improper fraction, because 1= 6/6
7/6 -6/6= 1 1/6
Answer:
7/6 would be 1 1/6
Step-by-step explanation:
To make it a number in general turn into a decimal.

do y’all know this one?
Step-by-step explanation:
For first triangle,
sin 45 = 3 / d
1 / root 2 = 3 / d
d = 3 root 2
For second triangle,
tan 60 = 7 / a
root 3 = 7 / a
a = 7 / root 3
What is the value of each expression?

Explanation:
Imagine that you cross out the top-most square for each step of each diagram. The squares not crossed out have the following counts: 1, 4, 9
This is the sequence of perfect squares. So the rule will have us take the number n, and square it to get n^2. Then we add on the squares we crossed out earlier. This explains the "plus 1" at the end to get the answer of n^2+1

How could writing a problem using an exponent be easier to understand than repeated multiplication?
Answer:
One reason, is because it clearer and easier to read.
Seeing two numbers (3^5) can let you know, in this example, 3x3x3x3x3 is harder to understand than 3^5.
3 is the number being multiplied, and 5 tells you how many times.

Give the largest whole number that could equal the length of the side in the picture.
Answer:
8
Step-by-step explanation:
We can use triangle inequality, let AC = x:
x+4 > 5
x+5 > 4
9 > x
Simplifying:
x>1
x>-1
9>x
Thus: 9>x>1
So the Largest whole number is 8
In 12 years, Janice will be 8 times as old as she was 2 years ago. How old is Janice
