Answer:

<DAB= 98

Step-by-step explanation:

Remark

I think you are supposed to assume that this is a parallelogram. In that case the two labeled angles are intended to be equal (one of the properties of a parallelogram).

Equation

2x + 36 = 3x - 5                    Add 5 to both sides

2x + 36 + 5 = 3x  - 5 + 5      Combine

2x + 41 = 3x                          Subtract 2x from both sides

2x - 2x + 41 = 3x - 2x           Combine

41 = x

Answer

<DAB = 2x + 36

<DAB = 2*41 + 36

<DAB = 82 + 36

<DAB = 98

In abc above,what is the length of ad​
Nezavi [6.7K]

Answer:

B

Step-by-step explanation:

First calculate BD using sine ratio in Δ BCD and the exact value

sin60° = \frac{\sqrt{3} }{2}, thus

sin60° = \frac{opposite}{hypotenuse} = \frac{BD}{BC} = \frac{BD}{12} = \frac{\sqrt{3} }{2} ( cross- multiply )

2BD = 12\sqrt{3} ( divide both sides by 2 )

BD = 6\sqrt{3}

-----------------------------------------------------------

Calculate AD using the tangent ratio in Δ ABD and the exact value

tan30° = \frac{1}{\sqrt{3} } , thus

tan30° = \frac{opposite}{adjacent} = \frac{AD}{BD} = \frac{AD}{6\sqrt{3} } = \frac{1}{\sqrt{3} } ( cross- multiply )

\sqrt{3} AD = 6\sqrt{3} ( divide both sides by \sqrt{3} )

AD = 6 → B

The Patel family looks at a map to plan their family vacation. They plan to travel from Smithville to Jonesville, which are 334i
denis23 [38]

Answer:

282.67\ mi  or  282\frac{2}{3}\ mi

Step-by-step explanation:

step 1

Find the total distance on a map between Smithville to Clarksville

334+514=848\ in

step 2

Find the actual distance

The scale on a map is equal to \frac{12}{4}\frac{in}{mi}

Applying proportion

\frac{12}{4}\frac{in}{mi}=\frac{848}{x}\frac{in}{mi}\\ \\x=848*4/12\\ \\x=282.67\ mi

Convert to mixed number

282.67\ mi=282\frac{2}{3}\ mi
