Answer 3

The first thing we'd have to know before finding the missing angle measure is, how many degrees does a triangle equal out to all together?

Answer 4

And the answer to that question is 180 degrees

Answer 5

***ALL TRIANGLES EQUAL 180 DEGREES***

No matter what shape or size.

Answer 6

With that said, lets get started...

Answer 7

If we have a triangle with one angle measure of 50 degrees and another angle measure of 65 degrees, how much does the missing angle measure?

Answer 8

Since we know that ALL triangles equal up to 180° , the missing angle in this triangle would have to equal 180 when added to 50° and 65°.

With that said, we need to set up our equation:

\[50° + 65° + x = 180°\]

Answer 9

Or you could use this alternate equation:

\[180- (50°+65°)= x\]

Answer 10

No matter which equation you use, you'll get the same answer, which is 65

Answer 11

The most important thing to remember when finding the missing angle in Triangles is that:

*All triangles Equal 180 degrees

Answer 12

Here is some important things to remember when finding the missing angle in Triangles:

*All triangles Equal 180 degrees

and

*Remember the formula, which is A + B + C = 180°
