<h2>○=> <u>Correct option</u> :</h2>

<h3>○=> <u>Steps to derive correct option</u> :</h3>
Angle 1 and angle 3 are vertically opposite angles.
We know that :
▪︎ Vertically opposite angles are always equal.
Which means :
Angle 1 = Angle 3
Thus, the measure of angle 3 = 70°
▪︎Therefore, the correct option is (D) 70
K is the amount that the function will go up or down.
It is typically the y intercept
Start with the Pythagorean theorem{A²+B²=C², A and B are the sides and C is the Hypotenuse/Longest Side.}
2²+4²=C²
4+16=C²
20=C².....{now square root both sides.√}
√20=√C²
4.472= C
P.S.: hope I helped :)
If you are looking for the value of X i believe it is 21.6
Subtract .10 from both sides to get
.25X=5.40
Then divide both sides by .25
