If G is the circumcenter of triangle ABC, find CG and FB. Round to the nearest tenth if necessary.

Stolb23 [73]

9514 1404 393

Answer:

CG = 19

FB = 14.7

Step-by-step explanation:

The circumcenter is equidistant from the triangle vertices, so GA = GB = GC.

The length of GA is given, so we have ...

GA = 19 = CG

Then the Pythagorean theorem can be used to find FB.

FB² +FG² = GB²

FB² = GB² -FG² = 19² -12² = 217

FB = √217 ≈ 14.7

Solving systems of equations by substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-3x - 3y = 3

y = -5x - 17

Step 2: Solve for x

Substitution

Substitute in y: -3x - 3(-5x - 17) = 3
Distribute -3: -3x + 15x + 51 = 3
Combine like terms: 12x + 51 = 3
Isolate x term: 12x = -48
Isolate x: x = -4

Step 3: Solve for y

Define equation: y = -5x - 17
Substitute in x: y = -5(-4) - 17
Multiply: y = 20 - 17
Subtract: y = 3
