This can be expanded through the tangent angle addition formula:

tan(α+β)=tanα+tanβ1−tan -α + tanβ

Thus,tan(x+y)=tanx+tany1−tan x tany

Hope it helps you

Answer:

  • See below

Step-by-step explanation:

<u>Angle opposite to 6 is complementary of α:</u>

  • 90 - α

<u>Similarly, angle opposite to side 4 of the triangle in the right side is:</u>

  • 90 - β

<u>Sum of the interior angles of the triangle on the bottom:</u>

  • 90 - α + 90 - β + γ = 180
  • γ = α + β
  • tan γ = tan (α + β)

<u>From the smaller triangles we get:</u>

  • tan α = 4/6 = 2/3
  • tan β = 3/4

<u>Use the identity below and find the value of tan γ:</u>

  • tan (α + β) = (tan α + tan β)/(1 - tan α tan β)
  • tan γ =
  • tan (α + β) =
  • (2/3 + 3/4) / (1 - 2/3*3/4) =
  • (17/12) / (1/2) =
  • 17/6 =
  • 2 5/6

Consider the following equation, bh+hr=25 when solving for r
Komok [63]
Solve for r.

You want to get r by itself on one side on the equal sign.

bh + hr = 25

Subtract bh from both sides.

hr = 25 - bh

Divide h on both sides.

r = 25 - bh / h

The two h's cancel each other out.

r = 25 - b

Hope this helps!

Answer:

x=38.5

Step-by-step explanation:

\sqrt{23^{2}- 18^{2}}   =\sqrt{205}

cos(x)=\frac{18^{2} +23^{2} -205}{2(18)(23)}

x=38.5(correct to the nearest tenth)
