Answer:
Length of other board metres
Step-by-step explanation:
Given: Length of board = metres
Length of board was divided into two.
Length of one piece = metres
Let = length of the other board
Length of the other board = Length of board - Length of one piece
So,
Thus, length of the other board metres
Angle 1 = 30°
Angle 2 = 90°
⇒ Angle 3 = 60°
So, it's right triangle. We can set the length of one side and get all other sides.
So, we have 1 triangle. If there are 2 or more triangles with the same data, all the triangles will be congruent because of : Two triangles are congruent if "ASA: Two interior angles and the included side in a triangle have the same measure and length, respectively, as those in the other triangle."
We want to find total to red
total just add
14+8+12=14+20=34
red=8
total to red=34:8 or 34/8=17/4=17:4
We are asked in this problem to determine the value of x from the expression given: 9+x/3x=5/6. we assume here that x is grouped with 9 otherwise, the expression would be invalid because x would be cancelled from the equation. So, we simplify
(9+x)/3x = 5/6we can cross multiply the terms to extract x eventually6*(9+x) = 3x*5we use associative property to multiply the terms54 + 6x = 15xwe then group the like terms54 = 15x - 6x = 9x54 = 9x we isolate x by dividing the whole equation by 9x =6The solution set of the problem then is equal to 6.
