Answer:
4 sqrt(2)
Step-by-step explanation:
radical 50 - radical 2
I rewrite in terms of sqrt (means the same thing)
sqrt(50) - sqrt(2)
sqrt(25*2) - sqrt(2)
We know that sqrt (ab) = sqrt(a) sqrt(b)
sqrt(25)sqrt(2) - sqrt(2)
5sqrt(2) - sqrt(2)
Factor out the sqrt(2)
sqrt(2) (5-1)
4 sqrt(2)
3 ( x + 2 ) + 2 = 8
3x + 6 + 2 = 8
3x + 8 = 8
3x = 8 - 8
3x = 0
x = 3
Hope it helps :)
Answer:
Step-by-step explanation:
These are logically difficult, so it makes sense to me you're asking about this.
so A = 1/2 (big arc - small arc)
and 360 = big arc + small arc
then
360 - small arc = big arc
so rewrite the top equation
A = 1/2(360-small arc -small arc)
63 = 1/2( 360 - 2 small arc)
2* 63 = 360 - 2 small arc
126 = 360 - 2 small arc
2 small arc = 360-126
2small arc = 234
small arc = 234/2
small arc = 117
x = 117°
