Anuta_ua [19.1K]

Answer:

26.8336 ≈ 26.83

Step-by-step explanation:

If x < 5, then we round down.

If x ≥ 5, then we round up.

2 decimal places is the hundredths place.

26.8336

3 < 5, so we round down

On an airplane, there are two seats on the left side in each row and three seats on the right side. There are 90 seats on the ri

vladimir2022 [97]

you would need to divide 90 by 3 because that is how many there are in each row.

you will get 30

then you need to multiply 30 by 2 becanse that is how many are in the rows on the left.

you will get 60,

so there are 60 seats on the left.

In triangle abc, if A=120 degrees, a=8 and b=3, then angle B=

CaHeK987 [17]

The angle of B is $\angle B=19^{\circ}$

Explanation:

It is given that $\angle A=120^{\circ}$ and $a=8, b=3$

To determine the $\angle B$ , let us use the law of sine formula.

Thus, we have,

$\frac{Sin A}{a} =\frac{Sin B}{b}$

Substituting the values in the formula, we have,

$\frac{Sin 120}{8} =\frac{Sin B}{3}$

Multiplying both sides by 3,we get,

$\frac{3(0.866)}{8} ={Sin B}$

Simplifying and dividing, we get,

$0.32475=Sin B$

Multiplying both sides by $\sin ^{-1}$ , we get,

$\sin ^{-1}(0.32475)=B$

Thus, $B=18.95^{\circ}=19^{\circ}$

Hence, The angle of B is $\angle B=19^{\circ}$
