Use the law of sines. find b to the nearest tenth. a. 45.0 b. 81.4 c. 65.4 d. 90.4 triangle cba line cb is 73 ∠b= 56°, ∠a=48°, b is a line between ac

b = 81.4 ⇒ answer (b)

Step-by-step explanation:

∵ In ΔABC

∵ CB = 73 , m∠B = 56° , m∠A = 48°

∵ AC = b

By using sin Rule:

∵ b/sinB = BC/sinA

∴ b/sin56 = 73/sin48

∴ b = (73 × sin56) ÷ sin48 = 81.4 ⇒ answer (b)

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
