DochEvi [55]3 years ago

Answer:

I think it is   20.75°

Step-by-step explanation:

An interesting problem!

the m arcVYX = 282°         so the m arcVYXV must equal 360°

so the m arcVX must equal 360 - 282  = 78°

I beleive m angle UVX - m arcVX = 78°

78 = 4x - 5

83 = 4x

20.75° = x      

I don't like this answer.  I would normally exspect whole numbers for most algebra problems

FrozenT [24]

Answer:

14 boys paid for the full year fee and 4 boys paid for the partial year fee

Step-by-step explanation:

Create a system of equations, where x is the number that paid for the $24 fee and y is the number that paid for the $16 fee:

24x + 16y = 400

x = y + 10

Solve by substitution by plugging in y + 10 as x:

24x + 16y = 400

24(y + 10) + 16y = 400

Solve for y:

24y + 240 + 16y = 400

40y + 240 = 400

40y = 160

y = 4

Then, plug in 4 as y to find x:

x = y + 10

x = 4 + 10

x = 14

So, 14 boys paid for the full year fee and 4 boys paid for the partial year fee.

Pythagorean Theorem a=11 b=60 c=?
zhuklara [117]

Answer:

61

Step-by-step explanation:

The Pythagorean Theorem is a fundamental in geometry that involves looking at two sides of a right triangle and finding out the length of it. Let's use the formula with the corresponding numbers.

The formula for this question would be c=\sqrt{a^2 + b^2}

Since we know that a = 11 and b = 60, we can do the following and substitute :

c = \sqrt{11^2 + 60^2}

11 squared is 121

60 squared is 3600

Now we need to add the two number together :

121 + 3600

3721

Since this number is under the square root, we have to square root it. :

\sqrt{3721}

61

Therefore c is equal to 61.

three trigonometric functions for a given angle are shown below csc theta = 13/12, sec theta = -13/5, cot theta = -5/12 what are
goldenfox [79]
We have that
csc ∅=13/12
sec ∅=-13/5
cot ∅=-5/12

we know that
csc ∅=1/sin ∅
sin ∅=1/ csc ∅------> sin ∅=12/13

sec ∅=-13/5
sec ∅=1/cos ∅
cos ∅=1/sec ∅------> cos ∅=-5/13

sin ∅ is positive and cos ∅ is negative
so
∅ belong to the II quadrant

therefore
<span>the coordinates of point (x,y) on the terminal ray of angle theta are
</span>x=-5
y=12

the answer is
point (-5,12)

see the attached figure
