Find the measure of . (to the nearest tenth) PLEASE I NEED HELP :((

Step-by-step explanation:

This is classic right triangle trig.  First decide how each side is related to the angle theta.  The side 7.7 is opposite the angle theta, while the side 14 is adjacent.  That is the tangent ratio by definition.  Setting up the tan ratio:

To find a missing angle on your calculator, hit the 2nd button, then the tan button and enter in 7.7/14 and hit enter.  You should get an angle measure of 28.8°

If you did not get 28.8 then you are probably in radians.  Check it in the "mode" of your calculator.

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
