Answer: D = 70
A = 30
Explanation: d is parallel to 70 degrees, 40 is parallel to e, and the whole set of angles is 180 so 180 - 2(70) + 2(40) = 30 so D = 70 and A = 30
1. Two angles are acute, while the other is square
2. They all add up to 180°
Answer: 10%
Step-by-step explanation:
The difference between his estimated and actual distance is 15 - 13.5 = 1.5
The percentage of error is the difference divided by the actual value.
1.5÷15 = 0.10
Converted to a percentage, it is 10%
Step-by-step explanation:
The answer is 8
Because you have to put each value of x given in the equation 3x = 24
So when you put the value 8
3(8) = 24
24 = 24
