Step-by-step explanation:
You have this rule, if there is < 30° then value of y is
y=12✓3:2
y=6√3
And Pitagora's theorem:
c²=a²+b²
In this case:
(12√3)²=y²+x²
Then x is:
x²= (12√3)²-y²
x²= (12√3)²-(6√3)²
x²=432- 108
x²= 324
x=✓324
x=18cm
Answer:
answer is 11.
Step-by-step explanation:
the median is always the middle
I can help you out, 8+10 x Square root of 2 is 22.1421356237 and then you simply take that and multiply it by 90* and y by 30* and i believe you have to use the Sin function on a calculator so
Sin90 X Sin 30
22.14 X Y
Cross multiply
Step-by-step explanation:
let George money will be X and Albert be Y
30$+x=y
x-50$=5y
30+x=y
x=y-30
(y-30)-50=5y
y-80=5y
y-5y=80
-4y=80
y=-20
x=-50
