C t//v u//w
this can be solved by analyzing the angles
angles on t and v are supplementary which makes them same side exterior angles
angles on u and w are supplementary making them same side interior angles

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 $10|y|$ .

If the sum of a number and 6 is multiplied by 5, the result is same as 9 times the number decreased by 2. find the number.

kogti [31]

Let's do an equation. 5(x+6)=9x-2. Now distribute into parentheses. 5x + 30=9x-2. Now -5x on both sides. New equation is 4x-2=30. Add 2 on both sides. 4x=28. Now divide by 4. X=8. Your number is 8
