Plaaaseee . i need to find the exterior angle measurement. i will mark brainliest

108

Step-by-step explanation:

Remark

You need to define Remote Interior Angle in order to solve this. The definition has two parts.

Interior: means means inside something. In this case it means inside the triangle.

Remote: (In this case) not connected to.

Equation

2a = a + 10 + 44               Combine the right side

Solution

2a = a + 54                       Subtract a from both sides

2a - a = a - a + 54             Do the subtraction

a = 54

Answer

a = 54

2a = 2*54

2a = 108

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
