Answer:

∠ B = 80.5°

Step-by-step explanation:

Since AB = AC then the triangle is isosceles with base angles congruent, so

∠ B = ∠ C , then

∠ B = \frac{180-19}{2} = \frac{161}{2} = 80.5°

Answer:

x + 3y = 15

Step-by-step explanation:

Line is passing through the points (3, \:4) = (x_1,\:y_1)\:and\: (9, 2)=(x_2,\:y_2)

Slope of line (m)= (2 - 4)/(9 - 3) = -2/6 = -1/3

Equation of line in point-slope form is given as:

y-y_1 =m(x-x_1)

Plugging the values of x_1,\: y_1\: and \: m in the above equation we find:

y-4 =-\frac{1}{3}(x-3)

\implies 3y-12 =-x+3

\implies x+ 3y =12+3

\implies \huge {\orange{\boxed{x+ 3y = 15}}}

This is the required equation of line in the form \red{\bold{ax + by = c}}

Find the equation of the line. <br> Use exact numbers.
AlekseyPX
The slope of the line (m) = 3/1  = 3  
and the y intercept is at (0,3)  that is y = 3  so b = 3

using the slope intercept form y = mx + b

m = 3 and b = 3

so answer is y = 3x + 3
