3. Given a right triangle, find the measures of all of the angles, in degrees, if one angle is a right angle and the measure of

the second angle is six less than seven times the measure of the third angle. Draw a labeled model of the triangle. Next, create an equation and solve it to find measurements of each angle. Use Google drawing to create a labelled model.

Answer:

90 degree

Step-by-step explanation:

Let represent the measure of the third angle. Then, − can represent the measure of the second angle. The

sum of the two angles in the right triangle will be °.

− + =

− =

− + = +

=

=

=

The third angle is and therefore measures °. Replacing with in − gives () − = − = .

Therefore, the measure of the second angle is °. The measure of the third angle is °.

Mariulka [41]

Let time be x distance be y

  • 140x=y-(1)
  • 290x=360-y-(2)

Put value in eq(2)

\\ \rm\longmapsto 290x=360-(140y)

\\ \rm\longmapsto 440x=360

\\ \rm\longmapsto x=1.2min

Put it in eq(1)

  • d=1.2(140)=168m

Write 0.28 in expanded form
Gala2k [10]
0.28=0.2+0.08
Or
0.28=2/10+8/100
Or
0.28=(2*1/10)+(8*1/100)
Or
0.28=(2*1/10^1)+(8*1/10^2)

Find the length of the third side. If necessary, round to the nearest tenth
Rufina [12.5K]

Answer:

30

Step-by-step explanation:

third side is the hypotenuse since it is opposite to 90 degree.

using pythagoras theorem

a^2 + b^2 = c^2

24^2 + 18^2 = c^2

576 + 324 = c^2

900 = c^2

\sqrt{900} = c

30 = c

therefore third side is 30.

1 A can in the shape of a cylinder has a diameter of 6 centimeters and a height of 10
Ronch [10]

Answer:

radius r = 3 cm

height h = 10 cm

volume V = 282.743339 cm^3

lateral surface area L = 188.495559 cm^2

top surface area T = 28.2743339 cm^2

base surface area B = 28.2743339 cm^2

total surface area A = 245.044227 cm^2

In Terms of Pi π

volume V = 90 π cm3

lateral surface area L = 60 π cm^2

top surface area T = 9 π cm^2

base surface area B = 9 π cm^2

total surface area A = 78 π cm^2

Step-by-step explanation:

Cylinder Formulas in terms of r and h:

Calculate volume of a cylinder:

V = πr2h

Calculate the lateral surface area of a cylinder (just the curved outside)**:

L = 2πrh

Calculate the top and bottom surface area of a cylinder (2 circles):

T = B = πr2

Total surface area of a closed cylinder is:

A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Agenda: r = radius

h = height

V = volume

L = lateral surface area

T = top surface area

B = base surface area

A = total surface area

π = pi = 3.1415926535898

√ = square root
