Answer:
1. Re-writing an equation to remove all the variables.
Step-by-step explanation:
Backtracking is the procedure required for solving problems that has series of parts combined as one. It involves the retracing each part after one or two parts has been solved to solve the whole problem.
In mathematics when given an equation with variables, the solution can be obtained by calculating the values of each variable. To determine the final solution sometimes requires substitution procedure.
The best option that describe backtracking in maths-sense is; re-writing an equation to remove all the variables.
Answer:
11/60
Step-by-step explanation:
It is convenient to use the relationship between sine, cosine, and tangent.
tan(x) = sin(x)/cos(x) = (11/61)/(60/61)
tan(x) = 11/60
Answer:
y = 8 and x = -32.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
To find the length of an isosceles triangle, you know that the angles of the triangle are 45-45-90, so let's use that triangle theorem.
Therefore, the length of the hypotenuse (BD) is 
, and x is equal to 8 (length of BC).
x=8
Therefore, would be the length of side BD.
