Answer:
BC = 5
BA11
angle D = 27
Step-by-step explanation:
If the triangles are similar
ABC ≅ DEF
That means AB ≅ DE
BC ≅ EF
and CA ≅ FD
We want to find AB so it is equal to DE
BC = EF = 5
BA = AB = DE =11
We also know the angles are equal
A = D
B = E
C = F
Angle A = angle D = 27
Answer:
Step-by-step explanation:
I think the best way is to split up the erasers before you do anything. That would mean there were 20 gift bags in all
If you did that, then each gift bag would contain 2 pencils with 10 left over.
Further 130 pens would divide up into 6 pens in each gift bag with 10 pens left over.
$72. The tip is $0.2 per $1, so you would pay $12 in tips plus the original $60
6 acts as the base. 15 acts as the height, because it extends from the base to meet vertex opposite the base at a 90° angle.
General formula for triangle area
a = 1/2 × b × h
plug in the numbers
a = 1/2 × 6 × 15
a = 90/2
a = 45
The area of the triangle is 45 units²
The plot of the PDF shows the distribution is symmetric. This means that the mean is the same as the median, and that the 50% of the distribution lies to other side of this mean, i.e.

For this distribution,
