If you mean find the one that has the number 1 on it your answer is 13.
90+77+x=180
167+x=180
X=13
Answer:
Subtract 2 from both sides.
Step-by-step explanation:
Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
> Also, note the equal sign, what you do to one side, you do to the other side of the equation.
First step is to subtract 2 from both sides of the equation:
3x + 2 (-2) = 29 (-2)
3x = 29 - 2
3x = 27
The second step is to divide 3 from both sides of the equation:
(3x)/3 = (27)/3
x = 27/3
x = 9

Answer:
z = 3.2 units
Step-by-step explanation:
sin 76°/z = sin 51°/2.6
cross-multiply to get:
z·(sin 51°) = 2.6·(sin 76°)
z = 2.6·(sin 76°) ÷ (sin 51°)
z = 3.2
The answer for the graph is x ≤ 5
