The Secant of angle A is -5/4. a) What quadrants could angle A be in? b) Determine the measure(s) of angle A

a) 2nd and 3rd quadrant

b) 143.13° and 36.87°

Step-by-step explanation:

Secant A = 1/cosecant A

sec A = 1/cosA

If Sec A = -5/4

Cos A = 1/(-5/4)

CosA  = -4/5

Since cos A is a negative values, hence the angle A will be in the 2nd and 3rd quadrant

b) If CosA  = -4/5

A = arccos(-0.8)

A = 143.13

A = 180 - 143.13

A = 36.87

Hence the measures of angle A are 143.13° and 36.87°

answer: 10 meter

step-by-step explanation:

need details

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
