Answer:
∠ B = 116°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , that is
∠ B + 28° + 36° = 180°
∠ B + 64° = 180° ( subtract 64° from both sides )
∠ B = 116°
Plug in
2(2) + 3(-3) + (-5)
4 + (-9) + (-5)
4 + (-14)
-10
Answer is -10
2x + 3y + z = -10
Answer:
b=7
Step-by-step explanation:
2(3b-1)= 40
divide both sides by 2
3b-1 = 20
then add 1 to each side
3b = 21
then divide both sides by 3
b = 7
then check 2(3*7-1) = 40
Step-by-step explanation:
Let x be the lost number then
x - 2/3 = 1/2
x = 1/2 + 2/3
x = (3 + 4)/6
x = 7/6
