Answer:

70 degrees

Step-by-step explanation:

total angle in a triangle is 180 degrees

180-40= 140

Angle b and c is total of 140 degrees

they are isosceles so their measurements would be same.

angle b and c is 140÷ 2 = 70

so angle b is 70 degrees

Find the slope of the line that passes through the points (−2/3, 3/4) and (5/6, −1/2).

EastWind [94]

Answer:

$-\frac{5}{6}$

Step-by-step explanation:

Use the slope formula : $\frac{y2-y1}{x2-x1}$

-1/2 is y2, 3/4 is y1, 5/6 is x2, and -2/3 is x1.

$\frac{-1/2-3/4}{5/6-(-2/3)}$

$\frac{-5/4}{5/6+2/3}$

$\frac{-5/4}{9/6}$

$\frac{-5}{4}$ ÷ $\frac{9}{6}$

$-\frac{5}{4}$ • $\frac{6}{9}$

$-\frac{5}{2}$ • $\frac{3}{9}$

$-\frac{15}{18}$

$-\frac{5}{6}$
