What is the value of x?

Mathematics
1 answer:
Paha777 [63]4 years ago

Answer: 12

Step-by-step explanation:

Since AC bisects ∠BAD, we know that ∠BAC and ∠CAD are equal to each other. To find x, we set them equal to each other.

9x-54=4x+6                              [subtract both sides by 4x]

5x-54=6                                      [add both sides by 54]

5x=60                                         [divide both sides by 5]

x=12

Now, we know that x is 12.

Solve for A, need this done in under a half hour please ;-;
jasenka [17]

Answer:

x=30, and angle A equals 132°.

Step-by-step explanation:

Since the angles are alternate-interior, both angles A and B equal the same amount. To figure out the value of <em>x</em>, you'd need to set up your equation like this:

5x-18°=3x+42°

You would need to solve for <em>x</em>, which should equal to 30.

Once you get your <em>x</em>, you need to plug it in into the equation of angle A, which is 5x-18°:

5(30)-18°

150-18°

Angle A = 132°.

Oksanka [162]

Answer:

= 10x² + 9x³

Step-by-step explanation:

I'm assuming you mean question 19

3x² + 5x³ + 7x² + 4x³    (rearrange to group like terms)

=3x² + 7x² + 5x³ + 4x³  (factor out common powers)

= (3+7)x² + (5+4)x³

= 10x² + 9x³
