X= 51 is the answer you need to remember that since they share a straight line you add the together to get 180 which is half a circle
Answer:
Step-by-step explanation:
If you would like to write the following in the math expression, you can do this using these steps:
a number ... n
eight less than four times a number ... 4 * n - 8
is less than 56 ... < 56
4 * n - 8 < 56
4 * n < 56 + 8
4 * n < 64 /4
n < 64 / 4
n < 16
The possible values of that number are less than 16.
Lets x and y are the 2 numbers
<span>One number is 5 more than another number: x = y + 5
</span><span>The sum of the two numbers is 43: x + y = 43
substitute </span>x = y + 5 into x + y = 43
x + y = 43
y + 5 + y = 43
2y = 38
y = 19
x = y + 5 = 19 + 5 = 24
answer
Two numbers are 19 and 24
Answer:
28%
Step-by-step explanation:
12+34+7=2856
Then, 2856/100 to get the percentage.
Answer:
Step-by-step explanation:
<u>Find the missing angle:</u>
- m∠L = 180° - 60° - 45° = 75°
<u>Use the law of sines to determine the lengths of the sides:</u>
- LM / sin ∠K = KM / sin 75°
- 12 / sin 60° = KM / sin 75
- KM = 12 sin 75° /sin 60° = 13.4 (rounded)
- KL / sin ∠M = LM / sin ∠K
- KL / sin 45° = 12 / sin 60°
- KL = 12 sin 45° / sin 60° = 9.8 (rounded)
<u>Find perimeter:</u>
- P = 12 + 13.4 + 9.8 = 35.2
