Write an explicit formula

1 answer:

4 0

Hey! I got you! So this is an arithmetic equation, and the common difference (how much it goes up by) is positive three. To find a sub 0- the first number of the sequence, you’ll subtract the first number shown by 3! This will show you 33! Now you input this into an equation and your answer will be 3n+33!

Please give brainliest!❤️

How do I solve for x and y

Alja [10]

Answer:

y=3, x=65

Step-by-step explanation:

Since there are little half circles on the angles, that means that they are the same value.

A triangle always adds up to 180 degrees.

You know that x + x + 50 = 180

That means that the 2 angles have to equal 130 degrees because 50+130=180.

If you divide 130 by 2 angles, you get 65 degrees per angle.

Finally, if you know that the two angles are equal, that means that the triangle is an isosceles triangle and the two side lengths are equal.
