2x +5=15
-5 -5
2x = 10
2 2 divide
Answer x=5
For this case what you have to take into account is the following trigonometric relationship:
TanB = b / a
We clear the value of b:
b = a * TanB
Substituting the values we have:
b = 10 * Tan (60)
b = 17.32 m
Answer:
b = 17.32 m
option a.
The solution of the expression ( -x²y)/(-xy)² will be ( -1 / y).
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given expression will be solved as below:-
( -x²y)/(-xy)² = ( -x²y)/(-x²y²)
Divide -x² by -x² it will become -y / y²
= -y / y²
Divide -y by -y² then it will become -1 / y.
= -1 / y
Therefore, the solution of the expression ( -x²y)/(-xy)² will be ( -1 / y).

Answer:
Hai
Step one
√3 × 2 = 2√3
√2 × 5 = 5√2
2√2 × 3√2 = 6√4 = 12
Step two
ill throw the numbers in square root to find them approximate value.
2√3 = √12
5√2 = √50
√12 = 3,4
√50 = 7
3,4+7+12 = 22,4
good luck(;
