C. Line m is a perpendicular<br> bisector. If EG=12 and FG=5,<br> of then how long is:
strojnjashka [21]

Answer:

EF = 13

GH = 5

EH = 13

Step-by-step explanation:

Given

The attached figure

EG = 12

FG = 5

Solving (a): EF

Since m is a perpendicular bisector, then <EGF and <EGH are right-angled.

So, EF will be calculated using Pythagoras theorem which states:

EF^2 = EG^2 + FG^2

EF^2 = 12^2 + 5^2

EF^2 = 144 + 25

EF^2 = 169

Take the positive square roots of both sides

EF = \sqrt{169

EF = 13

Solving (b): GH

Since m is a perpendicular bisector, then GH = FG

FG = 5

GH = FG

GH = 5

Solving (c): EH

Since m is a perpendicular bisector, then EH = EF

EF = 13

EH = EF

EH = 13
