in the linear equation the greatest power of the variables is 1 for example:2X+4 this is a linear equation as the greatest power of the variable X is 1 also by drawing it in a graph you will obtain a straight line
while in the quadratic equation the greatest power is 2 for instance:X^2+4X-3 this is a Quadratic equation because the greatest power of the variable X is 2 also by drawing it on a graph you will obtain a parabola which is a curve "an upward curve or downward curve"

A right triangle ABC with right angle at B and base BC is drawn. Length of AB is 12, length of BC is 11.5. A similar right trian

expeople1 [14]

Answer:

Option D is correct.

Length of PQ is 36 unit.

Explanation:

If the measures of two sides in one triangle are proportional to the corresponding sides in the another triangle and their including angles are congruent, then the triangles are similar.

Given: Right angle triangle ABC at B , Length of AB = 12 unit and length of BC = 11.5 unit and in right angle triangle PQR at Q , length of QR = 34.5 unit.

Also it is given that Angle A is congruent to angle P and angle C is congruent to angle R.

To find the length of QR:

It is given that ΔABC and ΔPQR are Similar triangle

then, by the definition of similar triangle:

$\frac{PQ}{AB} = \frac{QR}{BC}$
