What is angle DFE? 119 42 19 78

Mathematics
1 answer:
Liula [17]3 years ago
6 0

Answer:

∠DFE=119°

Step-by-step explanation:

step 1

Find the measure of angle BFD

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.

so

∠BFD=(1/2)[arc BD+arc CE]

substitute the given values

∠BFD=(1/2)[38°+84°]

∠BFD=61°

step 2

Find the measure of angle DFE

we know that

∠BFD+∠DFE=180° -----> linear pair (supplementary angles)

substitute

61°+∠DFE=180°

∠DFE=180°-61°=119°

What is the slope of the line that passes through (-3,4) and (-3,-4)
suter [353]

Answer:

undefined

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

    = ( -4-4)/( -3 - -3)

   = ( -4-4)/( -3+3)

   = -8/0

When we divide by zero, the answer is undefined so the slope is undefined

Determine the exact values of all three trigonometric functions of the angle 4.25pi
Margarita [4]

Answer:

Sin (4.25π)= 0.7071

Cos(4.25π)= 0.7071

Tan(4.25π)= 1

Step-by-step explanation:

\pi=180º (half circumference)\\ 2\pi= 360º (complete circumference)\\ 4\pi= 720º (2 complete cincumference\\ 4.25\pi= 720º + 45º (2 complete circumference + 45º)

Sin, Cos and Tan of 45º angle is the same with 1,2 or more circumferences.

So the result is the same for 45º angle.

So:

Sin (45º) = \frac{\sqrt{2} }{2}\\Cos (45º) = \frac{\sqrt{2} }{2}\\ Tan(45º) = 1
