Answer:
11 / 20
Step-by-step explanation:
3/4 - 1/5
You cannot perform this if you have two different denominator.
So multiply both pairs with each other's denominator.
3 × 5 = 15 1 × 4 = 4
4 × 5 = 20 5 × 4 = 20
Now we can perform subtraction.
15/20 - 4/20
15 - 4 = 11
11 / 20
The following option that is not a congruence theorem or postulate is B) AAA (angle angle angle).
Hope this helps, have a BLESSED and wonderful day, as well as a safe one too!

Answer:
1. Identifying parts of a triangle can help you find trigonometric ratios by seeing what side and angle measurements you have and if you have enough information to solve the triangle.
2. To use inverse trigonometric functions you should have to find the unknown measure of an angle of a right triangle when two side lengths are known. So, you simply use the same math as you would in trig ratios, but in a calculator you would have to click cos^-1, tan^-1, or sin^-1.
