If ∠R is given and the values of r and q are given, then explain whether the Law of Sines or the Law of Cosines should be used t

JulijaS [17]

Answer:

Law of Sines, two sides and an opposite angle are known

Step-by-step explanation:

We are given <R, which is an opposite angle to side r.

Side q is also given, which has an unknown opposite angle, <Q, of which we are required to find.

Since two sides and an opposite angle are known, The Law of Sines would be applied in solving for <Q.

Thus, the following would be used:

$\frac{sin(Q)}{q} = \frac{sin(R)}{r}$

molly is 4 years younger than Heidi. In 3 years, Heidi will be twice as old as Molly. How old are they now

ASHA 777 [7]

Answer:

Molly would be 1 years old.

Step-by-step explanation:

"In three years..."

(m+3) will be Molly's age then.

(h+3) will be Heidi's age then.

(h+3) = 2(m+3) :: given.

Subsitute what we know about m, which is it equal h-4.

(h+3) = 2(m+3)

(h+3) = 2m + 6

substitute m=h-4

(h+3) = 2(h-4) +6

h +3 = 2(h -4) +6

h +3 = 2h -8 +6

h +3 = 2h -2

h = 2h -8 +3

-h = -5

h = 5

Heidi is 5 years old now.

m = h-4

m = 5-4

m = 1

Molly is 1 years old now.
