What is the measure of ∠F?<br> What is the measure of ∠R?<br> What is the measure of ∠C?
DanielleElmas [232]
C= 43
I'm not sure what the measure of R is, but I think the measure of F is 55°. I'm not 100% sure, which I feel terrible about, but I am positive that C= 43

How many real solutions does the equation 8x^2 − 10x + 15 = 0 have?
Nimfa-mama [501]

Answer:

The correct option is (A) No real solution.

Step-by-step explanation:

The expression provided is a quadratic equation.

8x^{2}-10x+15=0

The roots of a quadratic equation are:

x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }

Here,

a = 8

b = -10

c = 15

The conditions to determine real and complex roots are:

  • If b^{2}-4ac then the quadratic equation has two complex roots.
  • If b^{2}-4ac>0 then the quadratic equation has two real roots.

Compute the value of b^{2}-4ac as follows:

b^{2}-4ac=(-10)^{2}-(4\times 8\times15)\\\\

             =100-480\\=-380\\

The equation has two complex roots.

Thus, the correct option is (A).
