A median cuts a leg of a triangle in half. So for instance, PF being a median means that DP and PE are congruent and have the same length. Consequently, each component triangle (that is, ∆DPC, ∆EPC, ∆EQC, etc) all have the same area.
If A is the area of ∆PCE, then the area of ∆PFE is 3A.
Take PF = 24 to be the base of ∆PFE, and take PC to be the base of ∆PCE. The area of any triangle is equal to 1/2 times the base times the height. But ∆PFE and ∆PCE share the same height (you can see this by dropping an altitude from the vertex E down to the line containing PF), so PC is 1/3 the length of PF, so FC must be 2/3 the length of PF.
So FC has length 2/3 × 24 = 16.

Sec x -tan x sin x =1/secx
Help me prove it
Answers
Answer:
L.H.S. = [tex]\frac{1}{cosx} -\frac{sinx}{cosx}sinx[/tex]
= [tex]\frac{1}{cosx} - \frac{sin^2x}{cosx}[/tex]
= [tex]\frac{1-sin^x}{cosx} = \frac{cos^2x}{cos x}[/tex]
= cos x = 1/secx
Step-by-step explanation:
Hey there!
Given;
sec x - tan x . sin x = 1/(sec x).
~ Taking LHS.
= sec x - tan x . sin x
= 1/(cos x) - (sin x/cos x) . sin x { Using formula sec x = 1/cos x and tan x = (sin x/cos x)}
~ Multiply (sin x) and (sin x).
[tex] = \frac{1 - { (\sin(x) )}^{2} }{ \cos(x) } [/tex]
~ Use formula 1-sin²x= cos²x
[tex] = \frac{ {cos}^{2} x}{ \cos(x) } [/tex]
~ Cancel cos x.
= cos x
= 1/sec x { cos x = 1/sec x}
→ RHS proved.

Step-by-step explanation:
im sorry if i couldnt help
Answer:
m is the slope, so it has a slope of 1. it gave you a point so it wants you to plug the point and slope into point-slope form and then solve for the equation to be in slope-intercept form so you can graph it.
point-slope form is: y -y1 = m(x -x1)
plug in the given values and solve
y - 4 = 1(x -4) (use the distributive property to get rid of the parenthesis)
y -4 = 1x - 4 (add 4 to both sides to isolate y)
y = 1x (1x is the same as x, so it's redundant to write 1x)
y= x (this is the equation of the line)
if you don't know how to graph y=x, whatever the y value is, the y value is. it's a straight line going through the origin.

A roofer leaned a 16-foot ladder against a house. If the base of the ladder is 5 feet from the house, how high up the house does the ladder reach?
Answers
Answer:
15.20feet
Step-by-step explanation:
Length of the ladder = 16foot (hypotenuse)
BAse of the ladder from the house = 5feet (adjacent)
height of the house = x (opposite)
Using the pythagoras theorem
hyp^2 = opp^2 + adj^2
16^2 = 5^2 + opp^2
256 = 25 + opp^2
opp^2 = 256-25
opp^2 = 231
opp =√231
opp = 15.20
Hence the house is 15.20feet high up the house

Answer:

Step-by-step explanation:
Equilateral triangles are
always
acute triangles. Yes, because acute is always 60 degrees, and equilateral is basically your average triangle, so its corners have 60 degrees.
Scalene triangles are
sometimes
acute triangles. Scalene triangles always dont have that sharp corner..they sometimes do, the sharp turn which is 60 degrees, ACUTE IS ALWAYS 60 DEGREES.
Right triangles are
never
acute triangles. A right angle cant be a acute, not 60 degrees..
Obtuse triangles are
always
