If vertices of a triangle are A (5, 0), B (x, y) and C (25, 0), what is the area of the triangle?(1) |x| = y = 10(2) x = |y| = 1

Elanso [62]

Answer:

$10|y|$

Step-by-step explanation:

We have been given that the vertices of a triangle are A (5, 0), B (x, y) and C (25, 0). We are asked to find the area of the given triangle.

We will use area formula for triangle with vertices A, B and C as given below:

$|\frac{A_x(B_y-C_y)+B_x(C_y-A_y)+C_x(A_y-B_y)}{2}|$

Upon substituting the given coordinates of points A, B and C in above formula, we will get:

$|\frac{5(y-0)+x(0-0)+25(0-y)}{2}|$

$|\frac{5(y)+x(0)+25(-y)}{2}|$

$|\frac{5y+0-25y}{2}|$

$|\frac{-20y}{2}|$

$|-10y|$

$10|y|$

Therefore, the area of the given triangle would be $10|y|$ .

Rama09 [41]

Answer:

See below.

Step-by-step explanation:

Statement 8. triangle SQR is congruent to triangle TQP

Reason 8. ASA

The only way to prove those two sides are congruent is to first prove that the triangles that contain those sides are congruent. Then you can use CPCTC to prove those sides congruent.
