Question

if tan theta = 3/4 then sec²A-tan²A​

Answer 1

Answer:

1

Explanation:

because we know sec²a-tan²a=1

Answer 2

• sec²A - tan²A = 1

Proof :-

• tan θ = 3/4 = opposite / adjacent = height / altitude
• hypotenuse = √(3)²+(4)² = √9+16 = √25 = 5
• sec θ = hypotenuse/adjacent = 5/4
• sec² A - tan² A = (5/4)² - (3/4)²
• = (25/16) - (9/16) = (25-9)/16 = 16/16 = 1
• sec² A - tan² A = 1
