Write the recursive formula for a sequence that starts with 50 and each term after increases by 20.

wriRedrawn the figure, refer to the ATTACHMENT with additional angles.

So, if we see the figure:-

Given that:-

The angles given are:-

70°

75°

65°

To find:-

The value of x.

Let's Do!

If now, you see the red angles marked byme, they are Vertically Opposite angles.

Let is find that first.

70 + 75 + y = 18070+75+y=180

145 + y = 180145+y=180

y = 180 - 145y=180−145

y = 35y=35

Now, the measure of red angle is 35°.

Now, as I said, they are Vertically opposite, so they are equal.

x + 35 + 65 = 180x+35+65=180

x + 100 = 180x+100=180

x = 180 - 100x=180−100

x = 80x=80

So, the value of x is 80°. Hence the final answer.
