zvonat [6]

Answer:

Step-by-step explanation:

A 45 degree angle in a right triangle produces 2 equal sides. In this case z and the perpendicular line are equal. So that's were we'll start. Then you move on to the 60 degree angle to get x and y.

Finding z

z^2 + z^2 = (24√2) Combine the left

2z^2 = 24^2 * 2 Divide both sides by 2

2z^2/2 = 24^2/2

z^2 = 24^2 Take the square root of both sides

√z^2 = √24^2

z = 24

Finding x and y

The perpendicular = 24. Because it is a 60 degree angle that's given, we can do this without a calculator.

Tan 60 = opposite over adjacent

sqrt(3) = Perpendicular / z Multiply both sides by z

z*sqrt(3) = perpendicular

The above calculation tells us the perpendicular is 24

z*sqrt(3) = 24 Divide by sqrt 3

z = 24/√3

z = 24/1.73

z = 8√3

Finding x

Use Pythagoras to determine x

Perpendicular^2 + (8√3)^2 = x^2

24^2 + 8^2*3 = x^2

576 + 192 = x^2

768 = x^2

√x^2 = √768

x = 27.71

What two formulas are necessary to find the area of a segment of a circle? i will name brainliest!!!!!!!

NeTakaya

The necessary formulas to get the area of a circle’s segment are the area of the circle’s sector and the triangle it is bounded by.

Hence the formula for the segment’s area is:Area of Segment = Area of sector – area of the triangle.

The formula of the area of a circle’s sector is:Area of Sector = $\frac{central-angle}{2}$ x (radius of circle)²

While the formula for the area of a triangle is:Area of Triangle = $\frac{1}{2}$ x base of triangle x height of triangle

Find the value of x and y

tiny-mole [99]

x° + 2y° = 180° ⇒ 2y° = 180° - x°

x° = 60° {three sides of the same lengh, means three angles=60°}

2y° = 180° - 60°

2y° = 120°

y° = 60°

Answer:

Step-by-step explanation:

5:9

x:40

what is the realationship between 9 and 40? -9x5=40

so 5x5=25 so x=25

5:9x5:5=25:40
