Answer: Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle
Step-by-step explanation:
That would mean Amanda is older because one-half would be 150%
Answer:
6x+12
Step-by-step explanation:
This is an equivalent expression as all I did was simplify the expression using the distributive property. (6(x)) + (6(2)) = (6x) + (12) = 6x + 12
shown in reverse to prove this is equivalent would look like this. 6x+12 = (6(x)) + (6(2)) = 6(x+2)
Let the length be 5x and width be 2x
Perimeter of rectangle= 2(length + bredth)
= 2(5x+2x) =126
∴ 2(7x)=126
14x = 126
x=9
Therefore, length = 5*9=45
and bredth= 2*9=18
