Answer:

360 inches or 30 feet

Step-by-step explanation:

A scale factor is the value which multiplied by a number scales the number larger or smaller. The blueprint has a wall height of 8 in. Using the scale factor 45, the actual height is 8*45 = 360 inches.

360 inches/ 12 inches  is 30 feet.

If mSW = (12x-5)°, mTV= (2x+7)°,and m angle TUV = (6x-19)°, find mSW
svet-max [94.6K]

Given:

Consider the below figure attached with this question.

m(arc(SW)) = (12x-5)°, m(arc(TV))= (2x+7)°,and measure of angle TUV = (6x-19)°.

To find:

The m(arc SW).

Solution:

Intersecting secant theorem: If two secants intersect outside the circle, then the angle on the intersection is half of the difference of the larger subtended arc and smaller subtended arc.

Using Intersecting secant theorem, we get

m\angle TUV=\dfrac{1}{2}(m(arc(SW))-m(arc(TV)))

6x-19=\dfrac{1}{2}((12x-5)-(2x+7))

6x-19=\dfrac{1}{2}(12x-5-2x-7)

6x-19=\dfrac{1}{2}(10x-12)

Multiply both sides by 2.

2(6x-19)=10x-12

12x-38=10x-12

12x-10x=38-12

2x=26

Divide both sides by 2.

x=13

Now, the measure of arc SW is:

m(arc(SW))=(12x-5)^\circ

m(arc(SW))=(12(13)-5)^\circ

m(arc(SW))=(156-5)^\circ

m(arc(SW))=151^\circ

Therefore, the measure of arc SW is 151 degrees.

Answer:

A and C are similar

Step-by-step explanation:

The sum of a triangles angles = 180

If you calculate the remaining angles, you will see that both A and C have the same angles and therefore are similar.

Write a few sentences about different ways to show subtraction for a problem like 32-15.
Sliva [168]
Well the way to subtract 32 by 15 is simple you have to line them up vertically and subtract. You also have to do some borrowing so basically it will look like this 
                                 32
                                -
                                 15
                              ________
