Answer:
48 cm ²
Step-by-step explanation:
area of a triangle is the base times the height and then then answer is divided by 2
bh/2
8 times 12 = 96/2 = 48 cm ²
just take -4.5 the right side
46
Rewriting the left hand side,
csc²t - cost sec t
= (1/sin²t)-(cost)(1/cost)
= 1/sin²t - 1
= 1/sin²t - sin²t/sin²t
= (1-sin²t)/sin²t
= cos²t/sin²t
= cot²t
