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: 3 x 7
Explanation:
So the question is asking you to multiply two prime numbers in order to get 21.
Since 3 and 7 are both prime numbers, you can express 21 as 3 x 7
Hope this helps! :)
Here is a list of prime numbers if it helps you. (prime numbers are in blue):
Given 736 hours, we are asked to find how many days are in it. This can be seen below.
Let x be the number of days in 736 hours. Since there are 24 hours in a day, we would have;

Thus,

Answer: 30.7
