Which is true about quadrant equations

 B                                                  

Step-by-step explanation:

Hey there !!!

the question is incomplete the full question is Which of the following statements is TRUE/CORRECT about Quadratic Equations? A quadratic equation is

with options

A) an expression with a single variable and degree 2

B) an equation with a single variable and degree 2

c) an equation with only degree to 2

D) an equation with single variable only

and the correct answer is B

because Quadratic Equation states that An equation with one variable and degree 2 is a Quadratic Equation. Only option b satisfies the two basic conditions of a quadratic equation i.e. one/single  variable and degree 2. Hence b is the correct answer.

Hope it helped

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
