Use the given information to solve the triangle for A = 150°, b = 4.8, a = 9.4

ELEN [110]

Well you can start by drawing a triangle with the information

the size of angle B can be found using the Law of Sine

$\frac{sin(150)}{9.4)} = \frac{sin(B)}{4.8}$

the size of angle C can be found using angle sum of a triangle.

The length of side c can be found using the Law of Cosines

$c^2 = 4.8^2 + 9.4^2 - 2 \times4.8\times9.4\times cos(C)$

hope it helps

Answer:

x=9

Step-by-step explanation:

PQ + QR + RS = PS

2x-6 + 1 + x-4 = 18

Combine like terms

3x -9 = 18

Add 9 to each side

3x-9+9= 18-9

3x = 27

Divide by 3

3x/3 = 27/3

x = 9

Patrice user a $15 gift certificate when she purchased a pair of sandals. After 8% sales tax was applied to the price of the san

ASHA 777 [7]

Answer:

The sandals cost before tax $25.

Step-by-step explanation:

Let us assume that the sandals cost before tax $x.

So, after giving an 8% tax the price will be $x(1 + \frac{8}{100}) = 1.08x$ .

If the $15 gift certificate on that after tax price and the final cost of the sandals becomes $12, then

1.08x - 15 = 12

⇒ 1.08x = 27

⇒ x = $25

Hence, the sandals cost before tax $25. (Answer)
