If Δ ABC = Δ DEF, which one of these is a pair of corresponding parts? CB and ED AC and DF

Mathematics
1 answer:
Radda [10]3 years ago
5 0

Answer:

AC and DF

Step-by-step explanation:

Corresponding sides as well as corresponding angles have a pair of same angles or sides that are in the same place in two different shapes that are similar.

Find attached the diagram used for solving the question

Since Δ ABC = Δ DEF

∠B corresponds to ∠E

∠A corresponds to ∠D

∠C corresponds to ∠F

As a result of the above:

Line AB corresponds to line DE

Line AC corresponds to line DF

Line BC corresponds to line EF

Therefore, if Δ ABC = Δ DEF, one of the pair of corresponding parts would be AC and DF.

HELP!! What is the approximate measure of angle x in the triangle shown?
Alex Ar [27]
<h3>Answer:   D)  130.5 degrees</h3>

=================================================

Work Shown:

c^2 = a^2 + b^2 - 2*a*b*\cos(C)\\\\10^2 = 5^2 + 6^2 - 2*5*6*\cos(x)\\\\100 = 25 + 36 - 60*\cos(x)\\\\100 = 61 - 60*\cos(x)\\\\100 - 61 = - 60*\cos(x)\\\\39 = - 60*\cos(x)\\\\\cos(x) = \frac{39}{-60}\\\\\cos(x) = -0.65\\\\x = \arccos(-0.65)\\\\x \approx 130.5416\\\\x \approx 130.5\\\\

Note: I used the law of cosines. Make sure your calculator is in degree mode.

Kala, Deandre, and Eric have a total of $119 in their wallets, Kala has $6 more than Deandre. Eric has 3 times what kala has. Ho
Tomtit [17]
Deandre = x
Kala = x + 6
Eric = 3(x+6)
x + x + 6 + 3(x+6) = 119
2x + 6 + 3x + 18 = 119
5x + 24 = 119
5x = 95, x = 19
Deandre has $19
Kala has 19 + 6 = $25
Eric has 3(25) = $75

melisa1 [442]

Answer:

x is less than 4

or

x is greater than 4

Step-by-step explanation:

-5x < -15x + 40 -5x < -15x + 40

+15x +15x -40 -40

10x < 40 -40 - 5x < -15x

÷10 ÷10 +5x +5x

× < 4 -40 < -10x

÷10 ÷10

4 < ×
