Answer:

125°°

Step-by-step explanation:

∠DFC is a vertical angle with ∠BFE. As such, it is the sum of the right angle and the one marked 35°.

∠DFC = 90° +35°

∠DFC = 125°

_____

<em>Alternate solution</em>

∠CFA = 90° = ∠CFB +∠BFA

∠CFB = 90° -35° = 55°

∠BFC and ∠CFD are a linear pair, so total 180°

∠CFD = 180 -55° = 125° = ∠DFC

3. E, F and G are collinear points. E is between F and G.

nikdorinn [45]

Answer:

Step-by-step explanation:

Collinear points are points that lies on the same straight line. If the points E, F and G are collinear points, then the three points lies on the same straight line.

If E is between F and G, the FE+EG = FG

EG = FG - FE

Given FE = 3 in and FG = 7 in

On substituting into the expression above to get EG;

EG = 7in - 3in

EG = 4in

Hence the length of EG is 4in

Answer:

Slope of line is $\pi$

Step-by-step explanation:

Given that the company logo has four concentric circles.

To plot the line on the graph take point as ( Diameter, Circumference )

Circumference of a circle is given by C= $\pi D$

Where D is the diameter.

To draw a line, we need at least two-point.

Now,

Take D=1

Circumference of a circle will be C= $\pi D=\pi$

Required point is (1, $\pi$ )

Take D=0

Circumference of a circle will be C= $\pi D=0 \pi$

Required point is (0,0)

The slope of line is given by s= $\frac{Y2-Y1}{X2-X1}$

Hence,

s= $\frac{Y2-Y1}{X2-X1}$

s= $\frac{0-[tex]\pi$ }{0-1}[/tex]

s= $\frac{[tex]\pi$ }{1}[/tex]

s= $\pi$

Thus, Slope of line is $\pi$

Cosα=x/L

L=x/cosα, we are told that the ladder base is 48 ft from the base of the wall and α=39° so:

L=48/cos39 ft

L≈61.76 ft (to nearest hundredth of a foot)
