Considering the similarity of triangles, the corresponding sides are:

\frac{DE}{AB} = \frac{EF}{BC} = \frac{DF}{AC}.

<h3>What are similar triangles?</h3>

If two triangles have the exact same angles, they are called similar, and the corresponding sides, that is, the sides adjacent to the same angles, have proportional lengths.

In this problem, the corresponding sides have equal ratios given as follows:

\frac{DE}{AB} = \frac{EF}{BC} = \frac{DF}{AC}.

Your uncle has 36 coins in nickels and quarters. The value of his nickels is 1/15 of the value of his quarters. Find the number
Ostrovityanka [42]

Answer:i

Step-by-step explanation:

Total coin = 36

Let the no. Of quarter = x

No. Of nickel = 1/15 × x = x/15

So, x + x/15 = 36

Multiply each terms by 15

15x + x = 540

16x = 540

x = 540/16

x = 33.75

Nickel is x/15 = 33.75/15 = 2.25

The answer is 27.6
angle version of the law of cosines:

cos(C) = (a^2 + b^2 − c^2)/2ab 

cos(A) = (b^2 + c^2 − a^2)/2bc

cos(B) = (c^2 + a^2 − b^2)/2ca


cos A = (b^2 + c^2 − a^2) / 2bc
cos A = (10^2+20^2-14<span>^2)/200
cos A = (100+400-196)/200
cos A = (500-196)/200
cos A = (304)/200
cos A = (1.52)
A = cos</span><span>^-1(1.52) = 40.54 degrees

cos B = (c</span>^2+a^2-b<span>^2)/2ca
cos B = (20</span>^2+14^2-10<span>^2)/280
cos B = (400+196-100)/280
cos B = (496)/280
cos B </span>≈ 1.77
B = cos<span>^-1(1.77) = 27.66 degrees

we have two methods left to find the measure of angle C:
method 1 :
cos C = (a</span>^2+b^2-c<span>^2)/2ab
cos C = (14</span>^2+10^2-20<span>^2)/140
cos C = (196+100-400)/140
cos C = (-104)/140
cos C </span>≈ -0.74

C = cos<span>^-1(-0.74) = 111.8 degrees

method 2: 40.54+27.66 = 68.2
180-68.2=111.8

The measure of angle A: 40.54
The measure of angle B: 27.66
The measure of angle C: 111.8
