Answer:
To solve for the trigonometric functions of x, we need to recall the ratios they represent as shown below.
sin x = O/H
cos x = A/H
tan x = O/A
where O stands for opposite, A for adjacent, and H for hypotenuse. So, for example, the sine of x is equal to the side opposite of angle x over the hypotenuse. The same goes for cosine and tangent. Using the diagram attached, we have the expressions of the trigonometric functions as shown below.
sin x = f/d
cos x = e/d
tan x = f/e

Answer:
JL = 14
Step-by-step explanation:
N represents the center of the rhombus
Then
N is the midpoint of the diagonal (line segment) JL
Then
JL = 2 × NL
= 2 × 7
= 14
It is only 1 proportion, and it is 1 problem.
10 8
---- = ---
X 4
1). It is 8x=40
2). Divide both sides
by 8
3). X=5
Hi there! I can help you with this.
6. Angle measurements:
x = 23
51 degrees
80 degrees
(2x + 3) = 49 degrees
8.
x = 30 degrees
3x = 90 degrees
2x = 60 degrees
x = 30 degrees
9.
x = 29 degrees
90 degrees
(2x - 2) = 56 degrees
(x + 5) = 34 degrees
Answer:
10 + 16 = 26
16 + 26 = 42
26 + 42 = 68
(C) the next three terms are 26, 42, 68
