The formula for the nth term of an arithmetic sequence is:
n_{th} \ term=a+(n-1)d
where a is the first term and d is the common difference.
Plugging the given values into the formula, we get:
20th\ term=3+(20-1)5=98
The answer is b. 98.

Can someone help me with this please?

Answer:

y=70°

z= 60°

w= 70°

Step-by-step explanation:

Since the two triangles are similar, we know that all of the corresponding angles must be the same.  On the triangle on the left, we can see that the angle formed between sides AB and AC is 60°.  This means that the same angle is formed at Z, which is in the same location on the triangle to the right.  From there, we can find the missing angle, W, from the difference of 180°.

180°-50°-60°=70°.

The same way we found Z, we can also find Y, since it has to be the same as W.

The number on the left is the x, and the number on the right is the y. so if the x is negative, then it would be on the x axis line. and you always use the x line first.
