Someone please solve for angle B

Mathematics
1 answer:
qaws [65]3 years ago
5 0

Answer:

<B=45°

Step-by-step explanation:

<A=<B (alternate angles)

5x-15=2x+21

5x-2x=21+15

3x=36

Dividing both sides by 3

x=12

Now

<A=5(12)-15

=60-15

=45°

<B=2(12)+21

=24+21

=45°

The sign would be negative

X is in the negative area meaning that when x/y and multiplied by y, it would stay negative since y is positive

Use the discriminant to determine how many real number solutions exist for the quadratic equation –4j2 + 3j – 28 = 0. A. 3 B. 2
Zepler [3.9K]

Answer:

C. 0

Step-by-step explanation:

–4j^2 + 3j – 28 = 0

The discriminant is b^2-4ac  if >0 we have 2 real solutions

                                                   =0  we have 1 real solutions

                                                   <0 we have 2 imaginary solutions

a = -4, b =3  c = -28

b^2 -4ac

(3)^2 - 4(-4)*(-28)

9 - 16(28)

9 -448

This will be negative so we have two imaginary solutions.

Therefore we have 0 real solutions
