Answer:

yes you are right! the answer is c

Step-by-step explanation:

**reminder: the hypotnuse is always your longest side**

first do 5 square = 25

then do 12 squared = 144

Rhett is solving the quadratic equation 0= x2 – 2x – 3 using the quadratic formula. Which shows the correct substitution of the

lesya692 [45]

Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

$ax^2+bx+c=0$

then the quadratic formula is

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

The given equation is

$0=x^2-2x-3$

Here, a=1, b=-2 and c=-3.

Substitute these values in the above formula.

$x=\frac{-(-2)\pm \sqrt{(-2)^2-4(1)(-3)}}{2(1)}$

$x=\frac{2\pm \sqrt{(-2)^2-4(1)(-3)}}{2(1)}$

Therefore, the correct option is 1.

Can someone help me with this??

Firstly , we will find

angle of inclination

Let's that angle as 't'

we are given

hypotenuse= 350

opposite =32

so, we can use sin

and find angle

$sin(t)=\frac{32}{350}$

$t=sin^{-1}(\frac{32}{350})$

we will get

$t=5.24$

so, angle of depression will also be

$=5.2$ ............Answer
