Answer:
5)
x=13.856
y=8
6)
u=4
v=3.464
Step-by-step explanation:
5)
y=hypothesis * sin(opposing angle)/sin(angle opposite of hypothesis)
y = 16*sin(30)/sin(90)
y=8
x=hypothesis * sin(opposing angle)/sin(angle opposite of hypothesis)
x=16*sin(60)/sin(90)
x=13.856
6)
sinA/(opposite of angle A) = sinB/(opposite side of angle B) = sinC/(opposite of side of angle C)
sin(90)/u= sin(30)/2
u *sin(30) = 2* sin(90)
u *sin(30) = 2
u=2/sin(30)
u=2/0.5
u=4
sin(60)/v= sin(30)/2
v *sin(30) = 2* sin(60)
v *sin(30) = 2 * 0.866
v * sin(30) = 1.73
v = 1.73/sin(30)
v = 3.464
Answer:
(29.99 + 18.65 + 32.59) 0.85 = 0
(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0
Step-by-step explanation:
The 15% off represents percentage discount. The relationship between percentage discount and total cost is given by the equation;
Actual cost - (Percentage discount) Actual cost = Total cost
The correct options are;
(29.99 + 18.65 + 32.59) 0.85 = 0
(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0
B, because -3^2 is not -9. -3*-3 = 9, square roots of negative numbers aren't possible, because no number squared can be equal to them. Instead, they are expressed in terms of "i", which is defined as
i^2 = -1
