Answer:

214°

Step-by-step explanation:

The arc subtending an angle at the centre are equal, that is

arc ED = 90° and

arc DF = 360° - (90 + 146)° = 360° - 236° = 124°

Thus

arc EDF = arc ED + arc DF = 90° + 124° = 214°

1 Expert Answer

Let x and y be the two numbers. Then by assumptions we have x+y=30 and x-y=20. Hence, y=x-20 and by plugging this into the first equation we obtain x+x-20=30 or 2x=50 or x=25 and y=5

Step-by-step explanation:

So, divide 30 by 2 . That gives you 15 for x, 15 for y. Now, you have difference of six, divide by two, that equals 3.

Answer:

$\displaystyle x=\frac{-8\pm\sqrt{(8)^2-4(4)(-221)}}{2(4)}\ \text{; x = 6.5 and x = -8.5}$

Step-by-step explanation:

Subtract the right side of the given equation to put it into standard form:

4x² +8x -221 = 0

Then the coefficients used in the quadratic formula are ...

a = 4
b = 8
c = -221

When these are filled into the form ...

$\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

the result is as shown above.
