<u>Trigonometry</u>

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

Angle θ = 70°

Opposite Leg = <em>x</em>

Adjacent Leg = 6

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

  1. Substitute in variables [tangent]:                                                                     tan70° = x/6
  2. [Multiplication Property of Equality] Multiply 6 on both sides:                      6tan70° = x
  3. Rewrite:                                                                                                             x = 6tan70°
  4. Evaluate:                                                                                                           x = 16.4849
  5. Round:                                                                                                               x ≈ 16.5

In right triangle ABC, B is the right triangle and m C = 30. If AC = 10 what is AB?
nekit [7.7K]

Using the law of sins:

Sin(angle) = Opposite Leg / Hypotenuse

Sin(30) = AB /10

Solve for AB:

AB = 10 * sin(30)

AB = 10 * 1/2

AB = 5

The answer is A.

A man got a 10% increase in his salary. If his new salary is 1,54,000, find his<br>original salary.​
daser333 [38]
The man’s original salary was 100%. when increased by 10% , it becomes 110% which is $154 000.

so,

110% -> 154 000
1% -> $1400
100% -> $1400 x 100
= $140 000

Two sides of a triangle are equal in length. The length of the third side is three meters less than the sum of the lengths of th
strojnjashka [21]
We have an isosceles triangle: 
The length of the sides are:
side₁=side₂=x
side₃=(x+x)-3=2x-3
Perimeter of a triangle=is the sum of the all sides.

we have this equation:
x+x+(2x-3)=29
4x=29+3
4x=32
x=32/4
x=8

The length of the third triangle will be: 2x-3=2*8-3=16-3=13

Answer: The length of the longest side of the triangle would be 13 meters.
