Hi there!

We know that angle MNL is 90 degrees, because a tangent is perpendicular to the radius. Therefore, all we need to do is set up a simple equation.

WORK:
180 = 90 + 71 + x
x = 19

ANSWER:
Angle MLN = 19 degrees

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

<span>NL←→ is tangent to circle M at point N
NL is perpendicular to MN
so
</span> ∠<span>NML = 90

</span><span> ∠MLN = 180 - 90 - 71
</span> ∠MLN = 19

frosja888 [35]

Answer:

Theory

Step-by-step explanation:

The theory refers to an explanation of something. It should be understandable also it contains some logic behind that

It is a formal, logical for events that involved the descriptions that related the things to one another

Therefore the above represent the theory

Hence, the same is to be considered

A man drove his car at 80km per hr for 1 and a quarter hrs .He rested for 45mins and then covered 240km, at the same time. Calcu
prisoha [69]

Answer:

Probably 128 km/h, but maybe 98.5 km/h. See below.

Step-by-step explanation:

What does "at the same time" mean?

If it means that he covered the 240 km in the same time as he convered the 80 km, then this is how you solve it:

80 km in 1.25 hour

240 km in 1.25 hour

Total distance: 80 km + 240 km = 320 km

Total time: 1.25 hour + 1.25 hour = 2.5 hour

average speed = (total distance)/(total time) = 320 km / 2.5 hour = 128 km/h

If it means he covered the 240 km in the same time he covered the 80 km plus the rest, then this is how you solve it:

80 km in 1.25 hour

240 km in 1.25 hour + 45 min = 240 km in 1.25 houir + 0.75 hour = 240 km in 2 hour

Total distance: 80 km + 240 km = 320 km

Total time: 1.25 hour + 2 hour = 3.25 hour

average speed = (total distance)/(total time) = 320 km / 3.25 hour = 98.5 km/h

Help I have to turn this in. In a couple hours

28. Surface Area

This is some sort of house-like model so for every face we see there's a congruent one that's hidden.  We'll just double the area we can see.

Area = 2 × ( [14×9 rectangle] + 2[15×9 rectangle]+[triangle base 14, height 6] )

Let's separate the area into the area of the front and the sides; the front will help us for problem 29.

Front =  [14×9 rectangle] + [triangle base 14, height 6]

          = 14×9 + (1/2)(14)(6) = 14(9 + 3) = 14×12 = 168 sq ft

OneSide =  2[15×9 rectangle] = 30×9 = 270 sq ft

Surface Area = 2(168 + 270) = 876 sq ft

Answer: D) 876 sq ft

29.  Volume of an extruded shape is area of the base, here the front, times the height, here 15 feet.  

Volume = 168 * 15 = 2520 cubic ft

Answer: D) 2520 cubic ft

14. The circle graph shows the results of an employment survey of 800
MariettaO [177]

Answer:

480 people were unemployed full time

Step-by-step explanation:

First thing to do here is to check the percentage of people that were unemployed full time

Looking at the graph, this is equal to 60%

This means that 60% of the total 800 are unemployed full time

Mathematically, that would be 60/100 * 800 = 480 people
