- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
Leg <em>a</em> = 9
Leg <em>b</em> = 40
Hypotenuse <em>c</em> = <em>d</em>
<em />
<u>Step 2: Solve for </u><em><u>d</u></em>
- Substitute [PT]: 9² + 40² = d²
- Exponents: 81 + 1600 = d²
- Add: 1681 = d²
- Isolate <em>d</em>: 41 = d
- Rewrite: d = 41
Answer:
1. Exponents- e.is the number of times the BASE NUMBER is multiplied by itself.
2. Term- a.is a number by itself or the product of a number and variable (or more than one variable).
3. Variables- d.letters or symbols used in place of a quantity we do not know yet.
4. Coefficient- c.the number in front of a variable
5. Constant- b.is a number that stays fixed in an expression

Answer:
Angle 2 = 64°
Step-by-step explanation:
Angle 2 = 180°-116° (int angles, 12//34)
=64°
Answer:
w = -7
Step-by-step explanation:
Isolate the variable, w. Note the equal sign, what you do to one side, you do to the other.
Divide -2 from both sides:
(14)/-2 = (-2w)/-2
(14)/-2 = w
Note that when you are dividing:
- 1 negative & 1 positive sign will result in a negative answer
- 2 negative sign will result in a positive
- 2 positive sign will result in a positive
In this case:
(14)/-2 = -7
-7 is your answer for w.
