Ответ:
32°
Step-by-step explanation:
soln:
let D be x then
since the triangle is an isosceles triangle base angles are equal so,
D+E+F=180°[sum of angles of a traingle]
or,x+x+116°=180°
or,2x+116°=180°
or,x=(180-116)/2
•°•x=32°
hence D=32°
Ответ:
(-2-4)/(5+16) = -6/21 or -2/7
Then plug in one of the points into y-y=m(x-x)
y + 2 = (-2/7)(x - 5)
Distribute the slope.
y + 2 = -2x/7 + 10/7
Subtract 2
y = -2x/7 - 4/7
So the answer is A.
