<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: Define</u>
<em>Identify variables</em>
<em>a</em> = 12 cm
<em>c</em> = 17 cm
<u>Step 2: Solve for </u><em><u>b</u></em>
- Substitute in variables [Pythagorean Theorem]: 12² + b² = 17²
- Evaluate exponents: 144 + b² = 289
- [Subtraction Property of Equality] Subtract 144 on both sides: b² = 145
- [Equality Property] Square root both sides: b = √145
- [√Radical] Evaluate: b = 12.0416
- Round: b ≈ 12.0
Answer:
ASA postulate
Step-by-step explanation:
You have 2 angles that are congruent and also 1 side is congruent
BUT
the side(S) must be in between the angles
Step-by-step explanation:
4(z+2)+4(z+3)
=4z+8+4z+12
=8z+20
by simplifying-
=2z+5
