Mathematics
1 answer:
nata0808 [166]2 years ago
3 0

Answer:

∠ DBC = 16°

Step-by-step explanation:

∠ ABD + ∠ DBC = ∠ ABC , substitute values

2x + 15 + x - 30 = 123 , that is

3x - 15 = 123 ( add 15 to both sides )

3x = 138 ( divide both sides by 3 )

x = 46

Thus

∠ DBC = x - 30 = 46 - 30 = 16°

The graph of an equation with a negative discriminant always has which characteristic?
spin [16.1K]

Answer:

The graph does not intercept the x-axis

Step-by-step explanation:

Hi there!

When the discriminant is positive, it means that in the quadratic equation, you <em>can</em> take the square root of this number and end up with two distinct solutions, one negative and one positive. The graph will intercept the x-axis twice.

When the discriminant is zero, it means that you won't be taking the square root of any number in the quadratic equation and you'll end up with two solutions that are equal, or just one distinct solution. The graph will intercept the x-axis once.

When the discriminant is negative, it means that the quadratic has no real solutions, meaning that it does not intercept the x-axis. It is impossible to take the square root of a negative number.

I hope this helps!

Find x<br> 27 degrees and 32 degrees will give brainlist
telo118 [61]

Answer:

x = 121°

Step-by-step explanation:

If you add up all the angles of a triangle, you get 180°.

So you must add up all the angles.

27+32+x=180\\\\59+x=180

Next you subtract 59 on both sides.

x=121

x should be 121°.

If you would like to check your answer, you can add up 27, 32, and 121. If it all equals to 180, then your answer is correct.
