we know that

The measurement of <u>the external angle</u> is the semi-difference of the arcs which includes

so

m∠LMN=\frac{1}{2}(270\°-90\°)=90\°

therefore

the answer is 90\°

4 cot theta<br>=<br>tan theta<br>how do I I find the value of quadrant?​
Ray Of Light [21]

Answer:

4cotα=tanα

4(1/tanα)=tanα

(4/tanα)=tanα

cross multiply

=> 4=tan²α

√4=√tan²α

±2=tanα

α=arc( tan) |2|

α=63.4° ( in first quadrant)

and

α=180+63.4=243.4 in the third quadrant

since we also found a negative answer( i.e –2) then α also lies in quadrants where it gives a negative value(i.e second and fourth quadrants)

α=180–63.4=116.6° in the second quadrant

α=360–63.4=296.6 in the fourth quadrant

therefore theta( in my case, alpha) lies in all four quadrants and is equal to:

α=63.4°,243.4°,116.6°and 296.6°

What is the perimeter of triangle ABC? Round each step to the nearest tenth. Please help me
Ad libitum [116K]

I would use the pythagorean theorem to find the lengths of each side. a² + b² = c².

Side AB is one we're looking for. If you make other right triangle with that same side you can see that one length is 4 and the other is 3. So, 4² + 3² = c² → 25 = c² → 5 = c. Side AB is length 5.

Side AC is another. Do the same with that side and you get that one length is 4 and the other is 3. (This is the same one as above) so side AC is length 5.

Side BC is the last one. One of the lengths is 1 and the other is 1 → 1² + 1² = c² → 2 = c² → 1.414213562 = c so side BC is approximately length 1.41.

Add each length up and you get a perimeter of roughly 11.4

Mr. Evans is paid $9. 20 per hour for the first 40 hours he works in a week. He is paid 1. 5 times that rate for each hour after
Dmitry_Shevchenko [17]
No, he almost earns $400
9.20 / 1.5 = 6.13
9.20 - 6.13 = 3.07
9.20 + 3.07 = 12.27
12.27 x 2.25 =  27.61
9.20 x 40 = 368
368 + 27.61 = 395.61
Mr. Evans earned $395.61 for 42.25 hrs.
