Answer:
x ≈ 2.55
Step-by-step explanation:
Since the triangles are congruent then DE ≡ AB , that is
DE = AB
76x - 7 = x + 184 ( subtract x from both sides )
75x - 7 = 184 ( add 7 to both sides )
75x = 191 ( divide both sides by 75 )
x ≈ 2.55 ( to the nearest hundredth )
The trigonometric expression tan² x + 1 = sec² x is proved by using the fundamental trigonometric formula and the definition of tangent and secant.
<h3>How to prove a derivate trigonometric formula</h3>
In this problem we must prove the existence of a trigonometric formula by means of definitions of trigonometric functions and the fundamental trigonometric formula.
Step 1 - Introduce the fundamental trigonometric formula and the definitions of tangent and secant:
sin² x + cos² x = 1, tan x = sin x / cos x, sec x = 1 / cos x
Step 2 - Divide each side of the formula by cos² x:
sin² x / cos² x + cos² x / cos² x = 1 / cos² x
(sin x / cos x)² + 1 = (1 / cos x)²
Step 3 - Use the definition of the two trigonometric functions:
tan² x + 1 = sec² x

We are given : Yesenia’s blocks represent 17.
<h3>Therefore, Yesenia has 1 ten block and 7 one blocks.</h3>
Misty has six more blocks then Yesenia and together they have 22 blocks.
<h3>Therefore, Misty has 6 ten blocks and 8 one blocks.</h3>
The total number of blocks represent 85.
Yesenia has blocks with a value 17.
<h3>Therefore, M
isty has clocks with a value of 85-17 = 68.</h3>
