Triangles ABC and CDE are mathmatecilly similar. work out the length of DE. WORK OUT THE LENGHT OF AB

Answers

Answer:

[tex]DE = 15[/tex]

[tex]AB = 6[/tex]

Step-by-step explanation:

Given

See attachment for triangles

Required

Determine the lengths of DE and AB

To solve for DE, we make use of the following equivalent ratio

[tex]AC : BC =CE:DE[/tex]

Substitute values

[tex]8:5 = 24:DE[/tex]

Express as fraction

[tex]\frac{8}{5} = \frac{24}{DE}[/tex]

Cross Multiply

[tex]DE * 8 = 24 *5[/tex]

[tex]DE * 8 = 120[/tex]

[tex]DE = 120/8[/tex]

[tex]DE = 15[/tex]

To solve for AB, we make use of the following equivalent ratio

[tex]AB : BC =CD:DE[/tex]

Substitute values

[tex]AB : 5 = 18 : 15[/tex]

Express as fraction

[tex]\frac{AB}{5} = \frac{18}{15}[/tex]

Multiply by 5

[tex]5 * \frac{AB}{5} = \frac{18}{15}*5[/tex]

[tex]AB= \frac{18}{15}*5[/tex]

[tex]AB= \frac{18}{3}[/tex]

[tex]AB = 6[/tex]

Answer:

m∠U = 36°

m∠V = 75°

m∠T = 69°

Step-by-step explanation:

(2x+14)+(6x+9)+(6x+3)=180

Combine like terms: 14x+26=180

Solve this equation: x=11

Use x=11 to find angles

∠U = 36°

∠V = 75°

∠T = 69°

You can add up all of these measurements to check. =180°

Answer:

The measures of the 3 angles are:Angle T = 69°Angle U = 36°Angle V = 75°

Step-by-step explanation:

The Triangle Sum Theorem states that the 3 angles of a triangle must add up to 180°.

We don't know the angles of the triangle, but we do know that the sum of all three unknown angles is 180°.

We set the three expressions together as equal to 180°.

6x + 3 + 6x + 9 + 2x + 14 = 180

Simplify

14x + 26 = 180

Subtract 26

14x = 154

x = 11

Now, we check our answer for x.

6(11) + 3 + 6(11) + 9 + 2(11) + 14 = 180

69 (measure of angle T) + 75 (measure of angle V) + 36 (measure of angle U) = 180

180 = 180 ✅

Note that once we found x, would substitute it in and get the needed measures. Since the needed measures add up to 180°, we know that our answer is correct.

The measures of the 3 angles are:Angle T = 69°Angle U = 36°Angle V = 75°

A cone has a volume 7065in and a height of 30 in what is the radius of the cone?use 3.14 for pi

Answers

Answer:

15 inches.

Step-by-step explanation:

V = 1/3 pi r^2 h

7065 = 1/3 * 3.14 * 30 * r^2

r^2  = 7065 / (1/3 * 3.14 * 30)

r^2 = 7065 / 31.4 = 225

r = sqrt 225 = 15.

Ok my bad last question anyways ❤️URGENT 25 EACH❤️

Answers

Answer:

angle ABC=72 degrees

Step-by-step explanation:

8x+6x+6x=180 degrees   (all triangles contain 180 degrees)

20x=180

x=9

angle ABC=8x or (8)(9)=72 degrees

Answer:

72°

Step-by-step explanation:

Angle A = 6x

Angle B = 8x

Angle C = 6x

The sum of all interior angles in a triangle is 180°, which means angles A, B and C add up to 180:

A + B + C = 180

substitute in the values for A B and C:

6x + 8x + 6x = 180

Simplify by combining like terms:

6x + 6x + 8x = 180

20x = 180

solve for x:

20x/20 = 180/20

x = 9

Since we know x = 9 and angle B = 8x, u can substitute in the value of x to find the value of angle B:

B = 8x

B = 8(9)

B = 72°

hope this helps!
