Answer:
see below
Step-by-step explanation:
Angle ACE = DCE since they are vertical angles
Angle A = Angle E parallel lines cut by a transversal form congruent alternate interior angles
Angle B = Angle D parallel lines cut by a transversal form congruent alternate interior angles
When all three angles are equal, the triangles are similar.
We can use ratios to find DE
DE CE
------- = ----------
AB AC
DE 8
------- = ----------
12 10
Using cross products
10 DE = 8*12
10 DE = 96
Divide by 10
DE = 9.6
Answer:
C. 19/18
Step-by-step explanation:
So the answer is C. 19/18
a. The formula for the area of rectangle is:
A = l w
so given that A = 3/5 m^2 and w = 2/5 m,
l = A / w
l = (3/5 m^2) / (2/5 m)
l = 3/2 m or 1.5 m
b. We take the ratio l/w:
l/w = (3/2 m) / (2/5 m)
l/w = 3.75
So the length is 3.75 times greater than width
