Answer:

  9.8

Step-by-step explanation:

The law of sines tells us ...

  g/sin(G) = e/sin(E)

Multiplying by sin(G) and filling in the given values, we have ...

  g = e·sin(G)/sin(E) = 22·sin(26°)/sin(81°) ≈ 9.76438

Side G is about 9.8 in length.

Answer: g = 9.8

Step-by-step explanation:

Considering the given triangle EFG, to determine side g, we would apply the sine rule. It is expressed as

a/SinA = b/SinB = c/SinC

Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes

e/SinE = f/SinF = g/SinG

Therefore

g/Sin 26 = 22/Sin 81

Cross multiplying, it becomes

gSin81 = 22Sin26

0.988g = 22 × 0.438

0.988g = 9.636

g = 9.636/0.988

g = 9.8

How can the order of operations be used to simplify expressions?
Lapatulllka [165]
Order of Operations, also known as PEMDAS (Parentheses, Exponents, Multiplication & Division, Addition & Subtraction), can help to simplify an equation by guiding you through the steps to solve it.

This is because it tells you to solve the parentheses. If there is none, but you've already done this, you solve for exponents, etc. 

The progressive soling of the equation not only makes it physically shorter, but also brings you closer to the answer.

Hope this helps, and I was the brainliest! :)

3 + (5 + 7)<br> Use the commutative property of operations to reverse the numbers in the expression.
xxTIMURxx [149]

Answer:

This has multiple solutions. For instance a solution could be (3 + 7) + 5 The Commutive Property is just switching up the numbers and put them in a different order/sequence.

hope i helped

Today only , a table is being sold at 34% discount. The sale price is $495. What was the price yesterday?
tekilochka [14]
In the given problem, it is given that the table is sold at a discount of only one day and that is today. so the table would be have been sold at its original price yesterday. The discount given today is 34% and the sale price for today is $495.
Let us assume the price of the table yesterday = x
Then we can write the equation as
x = 295 * (100/34)
  = 29500/34
  = 867.64
So the selling price of the table yesterday was $867.64.
