Answer:
The answer is A.
Step-by-step explanation:
Using the formula, sin(A+B) = sinAcosB + cosA sinB :
sin(A+B) = (0.29×0.91) + (0.96×0.42)
= 0.2639 + 0.4032
= 0.67 (2.dp)
Answer: D
Step-by-step explanation:
Formula: A = 2(wl+hl+hw)
A = 2(5*3 + 7*3 + 7*5)
A = 2(15 + 21 + 35)
A = 2(71) = 142 sq inches
Fourths, then b. Sorry if late.
