Greater=19
Smaller=3
Just use substitution
Answer:
166°
Step-by-step explanation:
Since ∠A = ∠B,
the equation below helps to find the value of x and angle A:
- 7x + 40° = 3x + 112°
- 7x - 3x = 112° - 40°
- 4x = 72°
- x = 72°/4
- x = 18°
- ∠A = 7*18° + 40° = 166°
Answer:
I think you should just follow what that person said
You can just substitute the m in the first equation
like this ; 2(10 - 2n) - 7n = -18.5
28-24=4/2=2
The answer is 2.
