Answer:
x = 466.7 ft
Step-by-step explanation:
The lower angle in the right triangle = 31° ( alternate angle )
Using the cosine ratio in the right triangle, with hypotenuse x
cos31° = 
= 
Multiply both sides by x
x × cos31° = 400 ( divide both sides by cos31° )
x = 
≈ 466.7
Answer:
yes
Step-by-step explanation:
because it can be expressed by a quotient
Answer: 85
Step-by-step explanation:
To solve this problem, we want to use the order of operations, or PEMDAS.
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
To be more specific, you evaluate the expression in the order from top to bottom. To clarify, it is multiply OR divide, depending on which comes first, left to right. This also applies to add OR subtract.
------------------------------------------------------------------------------------------------------------
20÷(5-3)+5²(3) [solve parenthesis]
20÷(2)+5²(3) [solve exponent]
20÷2+25(3) [solve multiply or divide, left to right]
10+75 [solve add or subtract]

-8
2/3(-21/3) + 2/3(-15/3)
-42/9 + -30/9
-72/9 = -8
