Hey!
Your answers are:
- 4 less than a number
- A number decreased by 4
Let k represent "a number". "k" is a variable, and variables are unknown.
-4 is subtracting 4. That means you're subtracting 4 from a number. -4 also means that the number is decreasing by 4. Therefore, those 2 are your answers.

The sum of the opposite interior angles is equal to the exterior angle.
So,
∠CAB + ∠ACB = ∠CBD
x + 40 + 3x + 10 = 6x
4x + 50 = 6x
2x = 50
x = 25°
∠CAB = x + 40 = 25 + 40 = 65°
Hence, the answer is D.
Answer:
Angle A is 37 degrees, Angle B is 82 degrees, Angle C is 61 degrees
Step-by-step explanation:
Exterior angles are the supplement of interior angles, so subtract 143 from 180 to find Angle A.
180 - 143 = 37
All angles add up to 180.
37 + 61 = 98
180 - 98 = 82
Angle B is 82 degrees.
