If m∠A = 56°, m∠B = 60°, and c = 8, what is the measure of side length b?

Alekssandra [29.7K]

Using the law of sines:

$\frac{b}{sin(B)}=\frac{c}{sin(C)}$

Solve for b:

$\begin{gathered} b=\frac{c\cdot sin(B)}{sin(C)} \\ so: \\ b=\frac{8\cdot sin(60)}{sin(64)} \\ b\approx7.708 \end{gathered}$

Answer:

7.708

Write the equation of the line that passes through the given lines (0,-2) and (4,1)

Gala2k [10]

Answer:

y = 3/4x - 2

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step 1: Define

(0, -2) y-intercept

(4, 1) random point

Step 2: Find slope m

$m=\frac{1-(-2)}{4-0}$

$m=\frac{1+2}{4}$

$m=\frac{3}{4}$

y = 3/4x + b

Step 3: Write linear equation

y = 3/4x - 2
