By law of Sines:

c / sinC = b / sinB
33 / sin145 = 7 / sinB
sinB = sin145 * 7 / 33
sinB = 0.122
B = 6.99

Find x. 14 in. 48 in. X = in.

Bad White [126]

Answer:

x = 50 in

Step-by-step explanation:

Since it is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2

14^2 + 48^2 = x^2

196 + 2304 = x^2

2500 = x^2

Take the square root of each side

sqrt(2500) = sqrt(x^2)

50 =x

x = 50 in

Which is the equation of Line B?

notka56 [123]

Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept
Slope Formula: $\frac{y_2-y_1}{x_2-x_1}$

So firstly, to find the slope of this equation, plug the two points, (1,1) and (-3,2), into the slope formula and solve as such:

$\frac{1-2}{1-(-3)}=-\frac{1}{4}$

Next, plug either one of the points into the x and y coordinates to solve for b as such:

$2=-\frac{1}{4}*-3+b\\2=\frac{3}{4}+b\\\frac{5}{4}=b$

Our final equation is $y=-\frac{1}{4}x+\frac{5}{4}$ , or the third option.
