Answer:

Step-by-step explanation:

( 7x + 6 ) and ( 9x - 6 ) are alternate interior angles.

Note : -

Alternate interior angles are equal.

9x - 6 = 7x + 6

9x - 7x = 6 + 6

2x = 12

x = 12 / 2

x = 6

Answer:

x = 6

Step-by-step explanation:

The 2 given angles are vertically opposite and are congruent , that is

9x - 6 = 7x + 6 ( subtract 7x from both sides )

2x - 6 = 6 ( add 6 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

10.) Kelly is flying a kite to which the angle of elevation is

jarptica [38.1K]

Answer:

61.08m

Step-by-step explanation:

Let " l " be the length of the rope and " θ " the angle at which it is raised. In other words:

l = 65m
θ = 70°

As you can see, there has been made a right angle triangle. So:

$sin70 = \frac{h}{l} \\ h = l \times sin70 \\ h = 65 \times 0.9397 = 61.08 \\ h = 61.08$

So the kite is approximately 61.08m above the ground.

In order to find the sin70° i used a calculator.

Trigonometry please help! work need to be shown

padilas [110]

Answer:

x = 5.56

Step-by-step explanation:

Apply trigonometric function to find x

Reference angle = 46°

Hypotenuse = 8

Adjacent length = x

Apply CAH:

Cos 46 = Adj/Hyp

Cos 46 = x/8

8 × Cos 46 = x

5.55726696 = x

x = 5.56 (nearest hundredth)

A garden table and a bench cost $852 combined. The table is $98 less than the bench. What is the cost of the bench?

Citrus2011 [14]

Answer:

Step-by-step explanation:

b=bench

852=b+(b-98) since the table is less than the bench by 98$

852-b=b-98

950-b=b

950=2b

475=b
