Hi there!
While there are no answer choices provided, here's how you can solve a problem like this.
To find the average of two numbers, you simply sum them up and divide by two!
For instance, to find the midpoint between 1 and 3, you add 1 and 3 to get 4, then divide by 2 which results in 2!
For 100 and 580, adding gives you 680, and dividing by 2 results in 340!
The average between 0.57 and 0.69 involves adding to get 1.26, then dividing by 2 yields 0.63!
Now, with percentages, for 45% and 67%, the addition gives you 112%, and dividing that by 2 will result in 56%!
So, for your answer options, just calculate the total and divide by two to determine which one results in 76%!
I hope this information helps!
Answer:
(-16x + 13)° + (-20x + 23)° = 180° (ángulo recto)
-16x° + 13° - 20x° + 23° = 180°
-36x° + 36° = 180°
-36x° = 180° - 36°
-36x° = 144°
-x° = 144°/(-36)
x° = 36°
