I think the answer is 21. I’m not sure but if I remember it’s 40 + 20 = 60. 180 - 60 = 120 and then it’s a vertical angle which is equal so then it would be 120 + 39 = 159. Then 180 - 159 = 21. Sorry if this is wrong I haven’t done this in a while. Have a good day!

Option C:
Step-by-step explanation:
Hello!
The sum of all angles in a triangle is 180°.
Add up all the angles and solve for x by setting the equation to 180°.
<h3>Solve for x</h3>
- ∠a + ∠b + ∠c = 180°
- (48 - x)° + (9x - 38)° + 90° = 180°
- 10° + 8x + 90° = 180°
- 8x = 180° - 90° - 10°
- 8x = 80°
- x = 10°
Now that we solved for x, we can plug it back into each equation to solve for each angle.
<h3>Angle A</h3>
<h3>Angle B</h3>
- 9x - 38°
- 9(10°) - 38°
- 90° - 38°
- 52°
<h3>Angle C</h3>
The answer is Option C:
Answer:
#1. 12x9x5+= 426
#2. 6x14.8= 784.14
#3. 6x6x8x8= 143.11

Hoped that helped!
Answer:
a = 6
Step-by-step explanation:
Area = 36 
Only one number will make this missing length true.
Obviously it's a square so one number x one number will equal to 36
6 x 6 = 36
2 because 3 meters is labor 6 feet and 2 is above 5'9'' so it's kinda understandable
