Victoria read a 160-page historical fiction novel followed by a science fiction novel of the exact same length. Her average read
postnew [5]

The answer is C: the average reading speed of the science fiction novel.

If x is her reading speed for the historical fiction novel, and her reading speed for the sci-fi novel is just two pages more than that of the historical fiction novel, then the equation to find out how fast she reads the science fiction novel would be x + 2, as you’re adding 2 to the reading speed of the historical fiction book (x)

Can someone help me please asap
riadik2000 [5.3K]

Answer:

A. 55°

B. 71°

C. 100°

D. 65°

E. 120°

F. 155°

G. 147°

H. 36°

I. 70°

J. 54°

K. 24°

L. 40°

Step-by-step explanation:

A. 180 - (90 + 35) = 55°

B. 180 - (34 + 75) = 71°

C. 180 - (43 + 38) = 100°

D. 180 - 50 = 130 / 2 = 65°

E. 180 - (90 + 30) = 60°

180 - 60 = 120°

F. 180 - (120 + 35) = 25°

180 - 25 = 155°

G. 180 - 145 = 35 + 112 = 148°

H. 180 - (40 + 26) = 144°

180 - 144 = 36°

I. 180 - (60 + 65) = 125°

180 - 125 = 55°

180 - (55 + 50) = 75°

180 - (75 + 35) = 70°

J. 180 - 116 = 64°

180 - (64 + 62) = 54°

K. 180 - (138 +18) = 24°

L. 180 - (80 + 60) = 40°

Cot^2x-csc^2x=-1 for all values of x true or falsse
Leno4ka [110]
Our basis for this equality is the pythagorean theorems of trigonometry. There are three equations for the pythagorean theorems. These are:

sin²x + cos²x =1
1 + tan²x = sec² x
1 + cot² x = csc² x

These are all derived from circle geometry on the cartesian plane. Now, the useful trigonometric property to be used is the third one. Rearranging this, we come up with

cot²x - csc²x = -1

This coincided with the given equation. Therefore, this is true. This is because it is already established from the pythagorean theorems.
