Answer:
-36
Step-by-step explanation:
plug in the letters for the numbers, then you get, -8 - 25 - 3. -8 - 25 is -33, then you subtract that to 3. so it should look like, -33 - 3. then simplified even more is -36.
25 is the greatest common factor of 75 and 25. 3 x 25 = 75.
Step-by-step explanation:
By Exterior Angle Theorem,
81° + b = 117°.
=> b = 117° - 81° = 36°.
