1) = -6

2) = 12

Step-by-step explanation:

1) = (2a⁴b³)² (-3ab⁷)³

= 2a⁸b⁶(-3ab⁷)³

= 2a⁸b × -3a³b²¹

= -6a¹¹b²²

Coefficient is -6.

(4a²b³)²(3ab⁷)⁵²

= 4a⁴b⁶×3a⁵²b³⁶⁴

= 12a⁵⁶b³⁷⁰

Coefficient is 12.

Step-by-step explanation:

Without complex calculation, we can find the coefficient by multiplying each coefficient of the product:

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
