Answer:
19.47°
Step-by-step explanation:
2 = opposite to A
6 = hypotenus
From trigonometry :
Sin A = opposite / hypotenus
Sin A = 2 / 6
Sin A = 1/3
A = sin^-1(1/3)
A = 19.47°
Yep his right and it is shown to me good
Answer:
30a²+11a−28
Step-by-step explanation:
(6a+7)(5a−4)
=(6a+7)(5a+−4)
=(6a)(5a) + (6a)(−4) + (7)(5a) + (7)(−4)
=30a² − 24a + 35a − 28
=30a² + 11a − 28
Hope I helped! (p.s. maybe brainliest answer)
