I have no idea how to do these geometry problems! if someone could explain to me how to do them that'd be awesome!

Murljashka [212]

"BISECT" an angle means split it into two equal angles.

In this diagram, you can see the long line GH, and they're telling us that GH "bisects" the big angle. That means that the angles on both sides of line GH are equal ... their measures are the same number of degrees.

Now, in the diagram, those angles on each side of GH are labeled. On one side, the angle is labeled 3x-3 and on the other side the angle is labeled 4x-14 . We don't know the measure of these angles because we don't know what ' x ' is. BUT ... we know that the two angles are EQUAL, because GH is a 'bisector'. Maybe we can use this clue to find ' x '.

We know their measures are equal, so we can write ...

3x - 3 = 4x - 14

Subtract 3x from each side: -3 = x - 14

Add 14 to each side: 11 = x

Look at that ! Is that cool or what ! ? ' x ' is 11 .

So the angle above GH is 3x-3 . . . that's 30°

and the angle below GH is 4x-14 . . . that's also 30° .

Yay ! They really ARE equal.

Now let's look back at the question:

a). 'x' is 11° . Angle FGH is the angle above GH, that's 30° .

b). Angle HGI is the angle below GH, that's also 30° .

c). Angle FGI is the whole big angle. That's 30° + 30° = 60° .

Circles M and K are congruent, QR, is congruent to LN and OP is congruent to VW. Find x and y

Alika [10]

Given, arc QR is congruent to arc LN and arc OP is congruent to arc VW.

And the expressions for each arc in the diagram also given as:

Arc QR = 2x - y, arc LN = 11 , arc OP= 10 and arc VW=5x+y.

Hence, we will get the system of equations as following:

Arc QR = Arc LN

2x - y = 11 ...(1)

Arc OP = Arc VW

5x + y = 10 ...(2)

Next step is to add the two equation to eliminate y so that we can solve the equations for x. Therefore,

2x+5x = 11 + 10

7x = 21

$\frac{7x}{7} =\frac{21}{7}$ Divide each sides by 7.

So, x= 3

Now plug in x=3 in equation (2) to get the value of y.

5(3) + y = 10

15 + y =10

15 + y - 15 = 10 - 15 Subtracting 15 from each sides.

y = -5

So, x=3 and y =-5
