Given: △ABC, E∈ AB m∠ABC=m∠ACE AB=34, AC=20 Find: AE

LenaWriter [7]

Answer:

AE = 11.76 units

Step-by-step explanation:

For better understanding of the solution, see the attached figure :

Given : E ∈ AB, m∠ABC = m∠ACE, AB = 34 and AC = 20

To find AE :

In ΔABC and ΔACE,

m∠ABC = m∠ACE ( Given )

∠A = ∠A ( Common angle for both the triangles )

By AA postulate of similarity of triangles, ΔABC ~ ΔACE

So, proportion of the corresponding will be equal.

$\implies \frac{AC}{AB}=\frac{CE}{BC}=\frac{AE}{AC}\\\\\implies\frac{AC}{AB}=\frac{AE}{AC}\\\\\implies\frac{20}{34}=\frac{AE}{20}\\\\\implies AE=\frac{20\times 20}{34}\approx 11.76$

Hence, AE = 11.76 units

The length of a lacrosse field is 15 yards less than twice the width, and the perimeter in 270 yards. The defensive area of the

sammy [17]

The defensive area is 510 square yards

Step-by-step explanation:

Let L be the length of the rectangle

and

W be the width

According to given statement

L = 2W-15

Perimeter = 270

$P = 2W+2L\\270 = 2W + 2(2W-15)\\270 = 2W + 4W -30\\270 +30 = 6W\\6W = 300$

Dividing both sides by 6

$\frac{6W}{6} =\frac{300}{6}\\W = 50\ yards\\\\and\\L = 2(50) -15\\= 100-15\\=85\ yards$

We have to find the area first to find the defensive area

So,

$Area = L* W\\= 85 * 50\\=4250\ square\ yards$

Defensive area = 3/25 of total area

So,

$=\frac{3}{25}*4250\\=3 *170\\=510\ square\ yards$

Hence,

The defensive area is 510 square yards
