Answer:
-7 7/15
Step-by-step explanation:
-11 2/3 -(-4 1/5) = -11 2/3 + 4 1/5. Now, we need to find the LCM of 3 and 5. The LCM of 3 and 5 is 15 because 15 is the lowest number that can divide both 3 and 5 separately and both results will still be whole numbers.
Now, we have -11 10/15 + 4 3/15.
-11 10/15 + 4 3/15 = -7 7/15.
15
A right angle is 90 degrees
The given angle is 75
90 + x + 75 = 180 (all three angles always add to 180 degrees)
165 + x = 180
180-165 = 15
15.75
