In Triangle ABC, The Measure Of

Answers

Answer 1

Answer:

128°

Step-by-step explanation:

As per diagram we have:

∠ECA ≅ ∠DCB - vertical anglesm∠ECA + m∠ABC = 180° - supplementary anglesm∠ECA = 3x + 5m∠ABC = x + 11

Substitute values and solve for x:

3x + 5 + x + 11 = 1804x = 164x = 41

Find the required angle measure:

m∠DCB = 3*41° + 5° = 128°
Answer 2

Answer:

m∠DCB = 3*41° + 5° = 128°

Step-by-step explanation:

2/5 - 1/7 = ???

find the least common denominator!

45 would be the least common demoninator!

so...

2 (7) / 5(7) - 1 (5) / 7 (5) = ?

14/ 45 - 5 /45 = ?

14 - 5 = 9

40 POINTS. When they form conical piles, granular materials such as salt, gravel, and sand settle at different "angles of repose," depending on the shapes of the grains. One particular 13-foot tall cone of dry sand has a base diameter of 38.6 fee
To the nearest tenth of a degree, what is the angle of repose of this type of dry sand?

A different conical pile of the same type of sand is 10 feet tall. What is the diameter of the cone's base?

Henley Landscaping Supply sells a type of sand with a 30° angle of repose for $32 per cubic yard. Find the cost of an 11-foot-tall cone of this type of sand. Show your work.

Answers

Answer:

34.0 degrees, 29.6 feet in Diameter.

This is a right triangle trigonometry question.

Use half of the diameter to form the base of the triangle (19.3 ft) with a height 0f 13.

Use Inverse Tangent function to find the angle of repose

round to 34.0

then use the angle of repose to solve trigonometric function of the tangent for the radius of the other cone.

switch denominator and tangent

multiply by 2 to get diameter of second cone

14.82*2≈29.6

phoebe and finn are sharing
some pies together, they have
eaten 29/12 of the pies fin ate
mor e pie than phoebe.phoebe
ate mor than 5/6 of a pie what
fraction of pie could phoebe and
finn each have eaten? show 3
combinations

Answers

Answer:

Let's define:

P = pies that Phoebe ate

F = pies that Finn ate

We know that together they ate 29/12 pies, then:

P + F = 29/12

We know that Finn ate more than Phoebe, then F > P.

And we know that Phoebe ate more than 5/6 of a pie, then:

P > 5/6.

Then we have the relations:

P + F = 29/12

P > 5/6

F > P

To find different combinations we can just give one of the variables a value.

We have a direct condition on P, which is:

P > 5/6

So we can just give P any value larger than 5/6 and find the value of F.

For example:

P = 6/6 = 1

Then:

F + 1 = 29/12

F = 29/12 - 1 = 29/12 - 12/12 = 17/12

And 17/12 > 5/6

So we meet the condition F > P.

Then we have the combination:

P = 1

F = 17/12

Now let's find another condition, this time let's use:

P = 5/6 + 1/12 = 10/12 + 1/12 = 11/12

Then:

F + 11/12 = 29/12

F = 29/12 - 11/12 = 18/12

And 18/12 > 11/12

Then we meet the condition:

F > P.

We have the combination:

F = 18/12

P = 11/12

Now for the last combination, we can use:

P = 5/6 + 3/12 = 10/12 + 3/12 = 13/12

Then:

F + 13/12 = 29/12

F = 29/12 - 13/12

F = 16/12

And 16/12 > 13/12

Then we meet the condition F > P

We have the combination:

F = 16/12

P = 13/12.
