Answer: 4/5 * 7^1/2 ==> 1st option
Step-by-step explanation:
3(7/25)^1/2-(28/25)^1/2+(63/25)^1/2=
3(7)^1/2 / 5 -(4*7)^1/2 / 5 +(9*7)^1/2 / 5=
3(7)^1/2 / 5 -2(7)^1/2 / 5 +3(7)^1/2 / 5=
(3-2+3)(7^1/2 / 5)=
4(7^1/2 / 5)=4/5 * 7^1/2 ==> 1st option
Answer:
60.28.
Step-by-step explanation:
We need the sine function because we are given the opposite side and we need the hypotenuse.
sin 71 = 57 / x
Cross multiply
x * sin 71 = 57
x = 57 / sin 71
= 60.28.
