The sum of the measures of three

Mathematics
1 answer:
Iteru [2.4K]3 years ago
8 0

Answer:

A

Step-by-step explanation:

Equation

2x + 3x + 8 + 7x - 2 = 90        

Solution

Combine like terms on the left

12x + 6 = 90                    Subtract 6 on both sides

12x = 90 - 6

12x = 84                         Divide by 12

x = 84/12

x = 7

________is an acute angle and sin theta and cos theta are given. Use identities to find tangent theta, cosecant theta, secant th
AnnyKZ [126]

Answer:

tangent theta = 12/5,

cosecant theta = 13/12

secant theta = 13/5

Cotangent theta = 5/12

Step-by-step explanation:

Given sine theta= 12/13, cosine theta= 5/13.

According to SOH CAH TOA

Sintheta = Opposite/Hypotenuse = 12/13

Cosine theta = Adjacent/Hypotenuse = 5/13

Opposite = 12, Adjacent = 5, Hypotenuse = 13

Tan theta = Opposite/Adjacent = 12/5.

cosecant theta = 1/sintheta = 1/{12/13}

cosecant theta = 13/12

secant theta = 1/cos theta = 1/{5/13}

Secant theta = 13/5.

Cotangent theta = 1/tan theta = 1/{12/5} = 5/12
