If anyone could do this it would be a great !
i just need the answers

1) 2x + 3x - 10 + 50 = 180

5x = 180 - 50 + 10 = 140

x = 140/5 = 28°

2) 3x + 15 + 4x + 5 + x = 180

8x = 180 - 15 - 5 = 160

x = 160/8 = 20°

Angle A = 3 (20) + 15 = 60 + 15 = 75°

3) x + 3x + 5x = 180

9x = 180

x = 20°

4) 48 + 2x = 180

2x = 180 - 48 = 132

x = 132/2 = 66°

5) 110 + 6x + 8x = 180

14x = 180 - 110 = 70

x = 70/14 = 5°

Angle C = 8 * 5 = 40°

Step-by-step explanation:

1) The sum of the angles in a triangle is 180 degrees. Therefore,

50 + 2x + 3x - 10 = 180

50 - 10 + 2x + 3x = 180

5x + 40 = 180

5x = 180 - 40 = 140

x = 140/5 = 28

2) 3x + 15 + 4x + 5 + x = 180

8x + 20 = 180

8x = 180 - 20 = 160

x = 160/8 = 20

3) 3x + 5x + x = 180

9x = 180

x = 180/9 = 20

4) The triangle is an isosceles triangle. The base angles are equal. Therefore,

x + x + 48 = 180

2x = 180 - 48 = 132

x = 132/2 = 66

5) 110 + 6x + 8x = 180

14x = 180 - 110 = 70

x = 70/14 = 5

The measure of angle C is

8 × 5 = 40

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
