Answer:
D. 159
Step-by-step explanation:
<span>An exterior angle of a triangle is equal to the sum of the opposite interior angles
x= 35</span>° + 58° = 93°
The general form of a quadratic equation is that which is expressed in a form,
ax² + bx + c = 0
To write the equation in its general form, eliminate the decimal by multiplying the equation by 10. It now becomes,
3x² + 50x - 70 = 0
The value of b is therefore 50 and the answer is the second choice.
subtraction:
5/8 - 1/8 = 4/8which reduces to 1/2 pound left
