The definition of a triangle is a polynomial with 3 sides and interior angles adding up to 180.

Using the definition, we can create an equation.

$180=42+31+x$

$180=73+x$

$x=107$

The measure of the third interior angle is 107 degrees.

Hope this helps.

頑張って!

Step-by-step explanation:

triangle angles = 180

In the figure above, if a:b:c = 3:4:1, what is the value of a?

Darina [25.2K]

Answer:

Step-by-step explanation:

The line is divided up into 3 parts, a part of 3, a part of 4, and a part of 1. If we had those parts together we get 8 meaning if we divided the line into equal parts that also fit into a, b, and c there would be 8. We can than divide the line into 8 parts which would be 10 each since a line is 180 degrees. Since a is 3 than a gets 3 of those parts meaning a would be 30

I hope this helps and please don't hesitate to ask if there is anything still unclear!

A commercial aircraft gets the best fuel efficiency if it operates at a minimum altitude of 29,000 feet and a maximum altitude o

aliya0001 [1]

Answer:

$x\geq 29,000$ and $x\leq 41,000$

Step-by-step explanation:

Let x be the altitude of a commercial aircraft

=>The expression " A minimum altitude of 29,000 feet" is equal to

$x\geq 29,000$

All real numbers greater than or equal to 29,000 ft

=>The expression " A maximum altitude of 41,000 feet" is equal to $x\leq 41,000$

All real numbers less than or equal to 41,000 ft

therefore, The compound inequality is equal to

$x\geq 29,000$ and $x\leq 41,000$

All real numbers greater than or equal to 29,000 ft and less than or equal to 41,000 ft

The solution is the interval [29,000,41,000]

How can you tell if three positive numbers form a<br> Pythagorean triple?

Sedaia [141]

Answer:

Since a Pythagorean triple is three positive integers a, b, and c such that (a^2)+(b^2)=(c^2), where a and b are the two legs, and c is the hypotenuse, first take the sum of the squares of the two legs and make an estimate. For example, 3, 4, and 5 is a Pythagorean triple since 9+16=25.
