<span>15-h)*h=40
15h-h^2=40
h^2-15h+40=0
solve for h by quadratic formula:
a=1, b=-15, c=20
ans:
h=3.47 or 11.53 cm (height)
b=15-h=11.53 or 3.47 cm (base)</span>
Answer:
Step-by-step explanation:
Suppose we have a triangle WXY whose internal angles are:
The sum of the measures of the angles must be 180°, thus:
Simplifying:
15x + 15 = 180
Subtracting 15:
15x = 165
Dividing by 15:
x = 11
Thus, the measure of angle Y is
Answer:
9 ft and 9 inches
Step-by-step explanation:
there are 12 inches in a foot
1ft = 12in
2ft = 24 in
3ft = 36 in
4ft = 48
and so on
9 ft = 108 inches which is the closes to 117.
So we have 9 ft
subtract 117 from 108, which is 9 inches left over
Hey there,
First, find the square root of the given equation.
Keep in mind that this is solved for k = 0 and 1.
Second, simplify.
Best of Luck!
