Answer:
A= 30
Step-by-step explanation:
This requires several steps.
First, you need to find the 2 other missing angles.
One can be found easily by substracting 130 from 180
so 180-130 = 50
The other angle is the same as 8x+4
Now set up your equation
180=3x-6 + 8x+4 +50
180 = 3x + 8x -6 + 4 +50
180+6-4-50 = 11x
132 = 11x
132/11 = x
12 = x
Now plug in 12 for x in your angle A
A=3x-6
A=3 * 12 - 6
A=36 - 6
A= 30
By setting up proportions and cross multiplying, the height would be 990.8.
No because if you do -5+10= it equals positive 5 and not a negative number.
10,000 is 8.33% of 120,000.
10,000 / 120,000 = 0.0833 * 100% = 8.33%
Assuming that the whole and percentage is given. find the value of the percentage.
120000 * 8.33% = 9996 ⇒ 10,000
If the percentage is given and its corresponding value. find the whole
10,000 / 8.33% = 120,048 ⇒ 120,000
Hello!
Some sample keys for the true or false three question test would be:
Keys are: False, False, False, True, True, True, False, False, True, True, True, False, False, True, False, True, False, True. False, True, True, True, True, False. Those are all the possible combinations for the answer key. (every 3 is a group). Hope this helps! Have a great day!
