<u>Trigonometry</u>

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Identify</u>

Leg <em>a</em> = 7.5

Leg <em>b</em> = 10

Hypotenuse <em>c</em> = <em>c</em>

<em />

<u>Step 2: Solve for </u><em><u>c</u></em>

  1. Substitute in variables [Pythagorean Theorem]:                                              7.5² + 10² = c²
  2. Rewrite:                                                                                                             c² = 7.5² + 10²
  3. Evaluate exponents:                                                                                         c² = 56.25 + 100
  4. Add:                                                                                                                   c² = 156.25
  5. [Equality Property] Square root both sides:                                                    c = 12.5

Blizzard [7]

Answer:

3 Questions

Step-by-step explanation:

After MM students took a test, there was a total of 64% of correct answers.

The tests contained a total of 50 questions.

Number of questions gotten to score 64%= 64% X 50 = 32 questions

If the next student wants to score 70%, he has to score

70% of the total score = 70% X 50 = 35

Therefore the least number of question more the student has to get right

=35-32

= 3 questions
