Hey there! :D
If m<A is the vertex, and it is isosceles, then the last two angles are equal.
All the angles in a triangle equal 180 degrees.
180-140= 40
40/2= 20
m<b= 20 degrees.
I hope this helps!

Answer:
<h2>D. (-2, 4)</h2>
Step-by-step explanation:
Put the coordinates of the points and check the equality.
2x + 3y = 8
A. (1, 4) → x = 1, y = 4
2(1) + 3(4) = 2 + 12 = 14 ≠ 8
B. (2, 2) → x = 2, y = 2
2(2) + 3(2) = 4 + 6 = 10 ≠ 8
C. (-1, 3) → x = -1, y = 3
2(-1) + 3(3) = -2 + 9 = 7 ≠ 8
D. (-2, 4) → x = -2, y = 4
2(-2) + 3(4) = -4 + 12 = 8 CORRECT
Answer:
When x = 8.4 and y = .8 then 4x + 8y = 40
Step-by-step explanation:
4x + 8y = 40
y = .8
Let's solve for x by substituting .8 for y (since y is given)
4x + 8(.8) = 40
4x + 6.4 = 40 Subtract 6.4 from both sides.
4x + 6.4 - 6.4 = 40 - 6.4
4x = 33.6 Divide each side by 4
4x/4 = 33.6/4 4 cancels on the left because 4/4 = 1
x = 33.6/4
x = 8.4
So when x = 8.4 and y = .8 then 4x + 8y = 40
