Hi there! I can help you with this!

a. Okay. So for questions like these, we have to combine like terms and solve this answer out. The problem would look like this: 10x - 6 =  24 + 9x. First, subtract 9x from both sides to get x - 6 = 24. Now, add 6 to both sides and you get x = 30. There is one solution and the equation is neither.

b. Repeat the same thing in this equation. 25 - 4x = 25 - 4x. First, add 4x to both sides to get 25 = 25. There are in infinite number of solutions and the equation is an identity.

c. 4x + 8 = 4x - 13. okay, subtract 4x from both sides, and you get 8 = 13, which is not a true statement. This problem has no solutions and is a contradiction.

Basically, to solve these problems, you have to add or subtract the "x" from the right side first to get the whole number by itself, and then if needed, add or subtract the whole number from the left side. Then, divide each side by the number the "x" is beside to isolate the "x". If the number is a positive, you subtract. If a number is negative, you add. If the number beside the "x" is negative and you have to divide, just divide by the negative. An identity equation has an infinite number of solutions, a contradiction equation has no solutions, and neither just simply means it's not an identity nor contradiction.

The measure of two opposite interior angles of a triangle are and. The exterior angle of the0x−14x+4triangle measures. Solve for
11111nata11111 [884]

Answer:

60 degrees

Step-by-step explanation:

Restructured question:

The measure of two opposite interior angles of a triangle are x−14 and x+4. The exterior angle of the triangle measures 3x-45 . Solve for the measure of the exterior angle.

First you must know that the sum of interior angle of a triangle is equal to the exterior angle

Interior angles = x−14 and x+4

Sum of interior angles = x-14 + x + 4

Sum of interior angles = 2x - 10

Exterior angle = 3x - 45

Equating both:

2x - 10 = 3x - 45

Collect like terms;

2x - 3x = -45 + 10

-x = -35

x = 35

Get the exterior angle:

Exterior angle =   3x - 45

Exterior angle = 3(35) - 45

Exterior angle = 105 - 45

Exterior angle = 60

Hence the measure of the exterior angle is 60 degrees

<em>Note that the functions of the interior and exterior angles are assumed. Same calculation can be employed for any function given</em>
