If cos∠B = sin∠A and m∠A = 32°, what is the measure of ∠B?

m∠B = 58°

Step-by-step explanation:

cos∠B = sin∠A (given)

cos∠B = cos(90°-∠A)

cos∠B = cos(90°- 32°)

cos∠B = cos 58°

m∠B = 58°

i dont know

step-by-step explanation:

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
