Answer:
7) x = 9°
8) x = 5°
9) x = 10°
10) x = 12°
Explanation:
7) By the angle subtended at the center is twice the angle subtended at the circumference, we have;
∠JLM = ∠JKV = 55°/2 = 27.5°
Similarly;
∠JML = ∠JVK = (18·x + 13)/2 = 9·x + 6.5
By exterior angle theory, we have;
13·x - 2 = 27.5 + 9·x + 6.5 = 9·x + 34
13·x - 9·x = 34 + 2 = 36
4·x = 36
x = 36/4 = 9
x = 9°
8) By the theorem angle formed on the outside of the circle by a tangent and a secant is equal to the difference of the arcs formed in between by the intercept of the tangent and the secant and the circle multiplied by half
Therefore;
8·x + 8 = (1/2) × (170° - (15·x - 1))
8·x + 8 = 85° - 7.5·x + 1/2
8·x +7.5·x = 85° - 8 + 1/2 = 77.5°
15.5·x = 77.5
x = 77.5°/15.5 = 5°
x = 5°
9) ∠TEU = ∠TWV = 175°/2 = 87.5°
∠TUU = ∠TYV = (5·x - 5)/2 = 2.5·x - 2.5
115° = 87.5° + 2.5·x - 2.5 = 90° + 2.5·x
2.5·x = 115° - 90° = 25°
x = 25°/2.5 = 10°
x = 10°
10) The measure of the intercepted arc formed by a chord is equal to twice the measure of the angle the chord forms with a tangent it intersects at the tangent point;
21·x + 18 = 2 × (The supplementary angle to ∠STU)
The supplementary angle to ∠STU = 180° - 45° = 135°
∴ 21·x + 18 = 2 × 135° = 270°
21·x = 270 - 18 = 252
x = 252/21 = 12
x = 12°.

Answer:
1. Weekly Khan Academy SAT Practice. Gets you used to the questions and format (exactly the same). It also gives feedback when you're done, so you know where to improve. Take at least one practice test half way through the time before your official SAT date. That way, you can know your projected growth. Before practicing, look at these tips for the English (https://blog.prepscholar.com/how-to-get-800-on-sat-reading-10-strategies-by-a-perfect-scorer) and Math (https://blog.prepscholar.com/how-to-get-800-on-sat-math-by-a-perfect-scorer) sections! They really help by giving a guide through your SAT practice!
2. As many as you would like. I don't believe it is open to students under the age of 13 and graduates from high school.
3. Above.
4. Very. Unless you plan on going to a school with a 60%+ acceptance rate. It doesn't hurt to score high, testing at least once each year to improve your score all the way until it is time for college applications. Don't settle less than a 1500. Unless, like I said, you plan on going to a non-competitive school (probably research that to get an idea of what you're aiming for).
5. It is a timed test (try and get used to reading and thinking fast), you only get points for what you get right (so no blank answers), it is a 4-hour long test (get lots of rest and eat a good breakfast that day so your stomach doesn't disrupt other testers!! I've had bad experiences... XD). More specific info can be found on CollegeBoard's SAT FAQ page.

How do I find the first four terms of this sequence?
Answers
Answer: See explanation
Explanation:
This is an arithmetic progression. In this case, we have been given the first term and the common difference. The formula to find the nth term will be:
= a + (n - 1)d.
Therefore, the first four terms are:
1st term = 300
2nd term = a + (n-1)d = a + (2-1)d = a + d = 300 + 50 = 350
3rd term = a + (n-1)d = a + (3-1)d = a + 2d = 300 + 2(50) = 300 + 100 = 400
4th term = a + (n-1)d = a + (4-1)d = a + 3d = 300 + 3(50) = 300 + 150 = 450
