Answer:
x = 24°
Step-by-step explanation:
What do the sum of all angles in a triangle add up to?
- The sum of all angles in a triangle add up to 180°.
First, let's find the missing angle of the big triangle (the angle next to 111°).
- 94 + 41 = 135
- 180 - 135 = 45°
Now, we can find the value of x given the smaller triangle's angle.
- x + 111 + 45 = 180
- x + 156 = 180
- x = 24
Therefore, x = 24°.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Number of females = f
Total number of people in audience = n
0.4n = f
f + (f+ 100) = n
2f + 100 = n
Find n:
f = 0.4n --> Replace f with 0.4n in the equation 2f +100 = n
2(0.4n) + 100 = n --> Multiply out the brackets
0.8n + 100 = n --> Subtract 0.8n from both sides
100 = 0.2n --> To get n, multiply both sides by 5
n = 500
There were 500 people in the audience.
