Log base 3 of 4 + log base 3 of 11= log base 3 of 4•11; Answers is 11
Answer:
Step-by-step explanation:
Triangle DEF is a right angle triangle.
From the given right angle triangle,
DE represents the hypotenuse of the right angle triangle.
With ∠E as the reference angle,
EF represents the adjacent side of the right angle triangle.
DF represents the opposite side of the right angle triangle.
To determine EF, we would apply
trigonometric ratio
Cos θ = opposite side/hypotenuse. Therefore,
Cos 49 = EF/8
EF = 8Cos49 = 8 × 0.6561
EF = 5.2488
Rounding to the nearest tenth, it becomes 5.2
Answer:
it would be 115
Step-by-step explanation:
there is no decimal so that means 115. if it was 115.1 then it would be 115 because it is closer to 115. now it is different if it was .5 and up because it would round up. anything above 5 will round up
