Answer:

94 degrees

Step-by-step explanation:

triangle is 180

so 180-74-20=86

The exterior angle is 74+20=94

94 is exterior angle

Answer:

x = 94°

Step-by-step explanation:

Any triangle has three angles whose measures add up to a total of 180°.

This triangle has two known angle measures. First, find the missing interior angle measure.

180 - (74 + 20)

180 - 94

86

The missing interior angle's measure is 86°. An exterior angle is supplementary to its adjacent interior angle, which means that the measure of the interior angle plus the exterior angle measure is 180.

180 - 86

94

Another way to find out a missing exterior angle measure is to simply add the measures of the two nonadjacent interior angles.

74 + 20

94

I hope this helped :)

To find the volume of a prism, use the equation V = area of base (B) x height (h).
damaskus [11]
<h3>Answer:  125 m^3</h3>

Work Shown:

V = (area of base) * (height)

V = B*h

V = 25*5

V = 125 m^3

Charles and Cynthia are purchasing a house. They obtained a 30-year, $535,000 mortgage at an annual interest rate of 3.6% compou
MA_775_DIABLO [31]

Answer:$4,369.17

Step-by-step explanation:

Compound interest (A)= P(1 + r/n)^not

A = compound interest

P = principal

r = rate

n = number of times the interest is compounded in a year

t = Time

From our data,

R = 3.6%

T =30 years

P = $535000

n= 12

A = 535000(1 + 0.036/12)^12*30

A= 535000*2.94

A= $1,572,900

In 30 years, we have (30*12) number of months = 360 months

To get the amount paid monthly, we divide the compound interest by the total number of months they'll repay the loan

Monthly payment = $1,572900/360 = $4,369.17

A 20 kg metal bar made of tin and silver lost 2 kg of its weight in the water. If 10 kg of tin loses 1.375 kg in the water and 5
Neko [114]

Answer:

Ratio of tin to silver in the bar is 2:3      

Step-by-step explanation:

We are given the following in the question:

10 kg of tin loses 1.375 kg in the water

Percentage of weight lost by tin  =

\dfrac{1.375}{10}\times 100\% = 13.75\%

5 kg of silver loses 0.375 kg

Percentage of weight lost by silver =

\dfrac{0.375}{5}\times 100\% = 7.5\%

20 kg bar loose 2 kg in water.

Percentage of weight lost by metal =

\dfrac{2}{20}\times 100\% = 10\%

Let x be the amount of tin and y be the amount of silver in bar.

Thus, we can find the ratio as:

\dfrac{x}{y} = \dfrac{\text{Silver's loss - Average loss}}{\text{Average loss - Tin's loss}}\\\\\dfrac{x}{y} = \dfrac{7.5-10}{10-13.75} = \dfrac{2}{3}

is the required ratio.

Morgarella [4.7K]

Step 1) Place the non-pencil part of the compass at point W and the pencil part at point X. Draw a circle. This circle has a radius of WX.

Step 2) Keep the compass the same width, place the non-pencil part at point X and the pencil part at point W. Draw a circle. This circle has the same radius.

Step 3) The two circles intersect at two other points, A and B. One point is above WX and the other is below. Connecting AB forms the perpendicular bisector.

See the diagram below.
