The reference angle of an angle is obtained by subtracting the angle with 360n where n is an integer until the resulting angle is below 360. In this case, 780 - 360 is equal to 420. this is still more than 360, hence 420 - 360 is equal to 60. the answer thus is 60 degrees.
Answer:

Step-by-step explanation:
We are given that an expression

We have to find an equivalent expression using distributive property .
Distributive property:

Using the property



Hence, the equivalent expression of the given expression is given by

The next two term is 13 and 16 respectively.
Step-by-step explanation:
here,
a1 = -2
a2 = 1
a3 = 4
a4 = 7
a5 = 10
So, d = <u>a2 - a1</u> = 1 - (-2) = 3
= <u>a3 - a2</u> = 4 - 1 = 3
Here, <u>Common difference</u> is <u>same everywhere</u> and the value of d is 3
Then,
<em>To find 6th term of this sequence</em>
<u>a6 = a5 + d</u>
= 10 + 3
a6 = 13
<em>To find </em><em>7</em><em>t</em><em>h term of this sequence</em>
<u>a7 = a6 + d</u>
= 13 + 3
a7 = 16
Thus, The next two term is 13 and 16 respectively.

Well, I wasn't down in Georgia for my 7th grade, but my mom told me before that it helps you to see how your progress is. No need to be worried :) You've got this!
Answer:
a₁ = 6
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= 
where a₁ is the first term and r the common ratio
Here
= 1530 and r = 2, thus
= 1530 , that is
a₁ (256 - 1) = 1530
255a₁ = 1530 ( divide both sides by 255 )
a₁ = 6
