The measure of an angle is three more then twice its supplement. What is the measure of the angle?

Answers

Answer 1
Answer:

Answer:

121 degrees.

Step-by-step explanation:

If the angle is x degrees then its supplement is 180-x degrees.

So we have the equation:

x = 2(180-x) + 3

x = 360 - 2x + 3

3x = 363

x = 121.

A machinist can produce 114 parts in 6 minutes.At this rate, how many parts can the machinist produce in 15 minutes?

Answers

114 parts / 6 min = X parts / 15 min 

114/6 = x/15 
cross multiply 

114 * 15 = 6 * x 

1710 = 6x 
divide both sides by 6 

1710/6 = 6x/6 

285 = x

Hope this helps! (:

Find the missing dimension. Round your answer to the nearest tenth. Please help me answer this problem. :) thanks.

Answers

The right answer for the question that is being asked and shown above is that: 

This can be answered using the Pythagorean Theorem.
h2 = a2 + b2
h = square root (8^2 + 5^2)
h = square root (64 + 25)
h = square root (89) in
h = 9.4 in

So the correct answer is 9.4 in given the dimension 5 inches and 8 inches.

Triangles 1 and 2 are similar What ratio relates a side length of triangle 1 to the corresponding side length of triangle 27. Fill the box to complete the ratio.___ to 12

Answers

First we have to see the name of similar triangles. And here triangles, CBA and FED are similar . Now we need to use the property of similar triangle, which is

Corresponding sides of similar triangles are in same proportion. Therefore in triangle FED, 12 is the measurement of side opposite to angle with measurement 28 . So in triangle CBA, side opposite to angle of measurement 28 is of length 8 .

So the ratio is

(8)/(12)
