Sum of 2 angles = 80°
Difference = 20°
If we take away 20° from the sum, both angles are equal
⇒80 - 20 = 60°
Divide by 2 to find the smaller angle:
60 ÷ 2 = 30
Add 20° to find the bigger angle:
20 + 30 = 50°
<u>One of the angle is 30° and the other angle is 50°</u>
Given that the sum of the two angles is 80°
⇒ Third angle = 180 - 80 = 100°
Answer: The 3 angles are 30° , 50° and 100°
Answer:
b should be the correct one
thank you
The correct way is to plug in the answer back into the equation and see if it results in the correct solution.
6x10^-4
move 4 places to the left
The answer is 0.0006,
20 with a number minus what will equal 9. ^_^
