(-8 3/4) +(-2 5/6) +(-1 1/5)
= -((8 +2 +1) +(45/60 +50/60 +12/60))
= -(11 +107/60)
= -(12 47/60)
= -12 47/60
Answer: 60 degrees
Step-by-step explanation:
the line is 180 degrees so minus 50 equals 130 minus 10 120 divide my 2 60

<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 Variables</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 24
Hypotenuse <em>c</em> = 40
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [Pythagorean Theorem]: x² + 24² = 40²
- [Subtraction Property of Equality] Isolate <em>x</em> term: x² = 40² - 24²
- Evaluate exponents: x² = 1600 - 576
- Subtract: x² = 1024
- [Equality Property] Isolate <em>x</em>: x = 32
Answer:
11.66
Step-by-step explanation:
Pythagorean theorem: a^2+b^2=c^2
6^2+10^2=c^2
36+100= c^2
sqrt(136)= sqrt(c)
c= 11.66
Answer:
x = 1/2
Step-by-step explanation:
8x-(4x-3)=5
Distribute the minus sign
8x -4x +3 = 5
Combine like terms
4x+3 =5
Subtract 3 from each side
4x+3-3 = 5-3
4x = 2
4x/4 = 2/4
x = 1/2
