Answers

Answer 1

Answer:

x = 5

Step-by-step explanation:

using the Pythagorean theorem:

x² = 13² - 12² = 169 - 144 = 25

x = √25 = 5

Answer 2

Answer:

x = 5.

Step-by-step explanation:

For a right triangle, use the Pythagorean Theorem, a² + b² = c², where a and b are the sides, and c is the hypotenuse.

a² + b² = c²

x²+ 12² = 13²

x² + 144 = 169

Subtract 144 from both sides.

x² = 25

x = 5.

Proof:

a² + b² = c²

5² + 12² = 13²

25 + 144 = 169

169 = 169.

The Fitzgerald paid $3,200 to heat their home in the year of 2018. By the end of the year 2019, they saw the cost of heating their home rose to $3,516 for the year. What could be use to find the difference in what they paid from 2918-2019?

Answers

Answer:

Substraction

Step-by-step explanation:

Given that  

The amount paid in the year 2018 is $3,200

And, in the year 2019 the amount paid is $3,516'

We need to find the differnece between two years so how we can find

Basically we need to subtract the amount i.e.

= $3,516 - $3,200

= $316

hence, the difference is of $316 from 2018 to 2019

As an unknown drone is detected by a radar dish hovering over a secure location in Washington dc the initial reading of the radar dish was detects the drone .The reading of the radar dish indicates an angle of elevation of 60 to the drone

Answers

Answer:

60° ; 30°

27.71 km

Step-by-step explanation:

Since we have a right angled triangle, and also the sum of the angles in a triangle is 180°

Angle of elevation is given as 60°

Hence, we have :

90°+60°+x ° = 180°

x = 180 - 150

x = 30°

The two acute angles are 60° and 30°

The altitude, h of the drone can be obtained thus :

Using trigonometry :

Sin θ = opposite / hypotenus

Sin 60 = h / 32

h = 32 * sin 60

h = 27.71 km

A trip, including hotel and air, is prices at $319.19 after tax. If the tax rate is 12%, calculate the price before tax that will result in this tax-included amount

Answers

Answer: $285

Step-by-step explanation:

Given

A trip costs [tex]\$319.19[/tex] after-tax inclusion

The rate of tax is 12%

Suppose x is the amount of charge before tax inclusion

We can write

[tex]\Rightarrow x+12\%x=319.19\\\Rightarrow x(1+0.12)=319.19\\\\\Rightarrow x=\dfrac{319.19}{1.12}\\\\\Rightarrow x=\$284.99\approx \$285[/tex]

The amount before tax inclusion is $285
