Consider the triangle.<br> 45°<br> 80°<br> Find the measure of the unknown third angle.

Elina [12.6K]

Answer:

$55 \degree$

Step-by-step explanation:

Let the unknown angle be x

As the interior angles in a triangle are added up to 180°

$x + 45 + 80 = 180 \\ x + 125 = 180 \\ x = 180 - 125 \\ x = 55 \degree$

Hope this helps you.

Let me know if you have any other questions:-)

What is the probability of rolling a die and having it land on a factor of 30?

Daniel [21]

Answer:

So, since there is an equal chance to roll any number on a six sided die, that means the chance of rolling any one number is one out of 6 or 1/6. You can see that with a diagram. Now, rolling two different numbers in a specific order you can tell with a diagram is 1/36.
