The relation between the secant and tangent is used to prove the equation. The detailed description is given below.
<h3>What is trigonometry?</h3>
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The equation is given below.
tan⁵ x = tan ³ x sec² x - tan³ x
Taking tan ³ x common then we have
tan⁵ x = tan ³ x (sec² x - 1)
We know that sec² x - 1 = tan² x, then we have
tan⁵ x = tan ³ x (tan² x)
tan⁵ x = tan⁵ x
Hence proved

Answer:
120 dollars ($120)
Step-by-step explanation:
(x = original price)
(0.8 is from 0.2 (20 percent) being discounted, meaning 96 is 80% {0.8} of the original price)
x × 0.8 = 96
÷ 0.8 ÷0.8
x = 120
check: 120 × 0.2 = 24
(20 percent of 120 is 24)
120 - 24 = 96
So, the original price was 120 dollars
----
remember: percentage can be found by multiplying by 0.percentage
for example, 10% of 100 = 100 × 0.10 = 10
also written as: 100 × 0.1 = 10
Answer:
S = -6
Step-by-step explanation:
s + 1/4s = -6 -3/2
5/4 s = -12/2 - 3/2
5/4 s = -15/2
5/4 s = -30/4
5s = -30
s = -30/5
s = -6
