The 3 angles form the straight line AB. A straight line equals 180 degrees.

The 3 angles when added together need to equal 180:

2x + 65 + (x + 65) = 180

Simplify by combining like terms:

3x + 130 = 180

Subtract 130 from both sides

3x = 50

Divide both sides by 3

X = 50/3

X = 16 2/3 (16.66667 as a repeating decimal)

Now you have x if you need to solve all the angles replace x with its value and sole:

2x = 2(16 2/3) = 33 1/3

X + 65 = 16 2/3 + 65 = 81 2/3

Step-by-step explanation:

2x+65°+(x+65°)=180° ( sum of angle of straight angle )

3x+65°+65°=180°

3x=180°-130°

3x= 50°

now,

i) 2x=2*50=100°

ii) (x+65°) = 50+65 =115°

plz mark me brainiest and thanks

have a good day ahead...

Answer: \frac{2x}{15}

This is the fraction 2x/15 which can be read as 2x over 15

=====================================================

Work Shown:

Divide \frac{14x^2}{15}over 7x to get

\frac{14x^2}{15} \div 7x = \frac{14x^2}{15} \div \frac{7x}{1}\\\\\frac{14x^2}{15} \div 7x = \frac{14x^2}{15} \times \frac{1}{7x}\\\\\frac{14x^2}{15} \div 7x = \frac{14x^2*1}{15*7x}\\\\\frac{14x^2}{15} \div 7x = \frac{7x*2x*1}{15*7x}\\\\\frac{14x^2}{15} \div 7x = \frac{2x}{15}\\\\

You can think of it as dividing 14x^2 over 7x and that results in 2x. Then you place that result (2x) over 15 to end up with 2x/15
