What is the area of a right triangle with the given vertices? a(3,1) , b(5,4) , c(6,−1)

square units

Step-by-step explanation:

We are given that vertices of a right triangle are A(3,1) ,B(5,4) and C(6,-1).

We have to find the area of triangle.

We know that area of triangle=

Substitute the values in the formula then we get

Area of right triangle =

Area of right triangle =

Area of right triangle = square units

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
