Answer:
19.47°
Step-by-step explanation:
2 = opposite to A
6 = hypotenus
From trigonometry :
Sin A = opposite / hypotenus
Sin A = 2 / 6
Sin A = 1/3
A = sin^-1(1/3)
A = 19.47°
(x+2/5)7=63/10
then divide both sides by 7
x+2/5=63/70
subtract 2/5 from both sides
and x= 1/2
*x=original number
Answer:
Step-by-step explanation:
n x 5
Answer:
190
Step-by-step explanation:
20 percent is 1 fifth of 100 percent so 38 would be 1 fifth. so multiply by 5
