Why is angle 3 congruent to angle explain why

kolezko [41]

Answer:

Angle 3 is = to angle 2 because:

Angle 3 & angle 7 are corresponding angles, meaning they have the same measure.

Angle 7 & angle 2 are vertical angles, meaning they also have the same measure.

Therefore, if angle 7 is equal to angle 3, then angle 2 must also be equal to angle 3.

Hope this helps! Have a great day!

The length of a suitcase is 36 inches . The diagonal of the suitcase is about 51 inches . What is the width of the suitcase ,rou

Mrrafil [7]

Given:

The length of a suitcase is 36 inches.

The diagonal of the suitcase is about 51 inches.

We need to determine the width of the suitcase.

Width of the suitcase:

The width of the suitcase can be determined using the Pythagorean theorem.

Thus, we have;

$d^2=l^2+w^2$

where d is the diagonal, l is the length and w is the width.

Substituting the values, we get;

$51^2=36^2+w^2$

Squaring the terms, we have;

$2601=1296+w^2$

Subtracting both sides by 1296, we get;

$1305=w^2$

Taking square root on both sides, we get;

$36.12=w$

Rounding off to the nearest inch, we get;

$36=w$

Thus, the width of the suitcase is 36 inches.

MAVERICK [17]

Answer:

$15\ units$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and the corresponding angles are congruent

In this problem Triangles PQT and RQS are similar by AA Similarity Theorem (The three angles are congruent)

therefore

$\frac{12}{16}=\frac{x}{20}\\ \\x=12*20/16\\ \\x=15\ units$

Х 30° Calculate the size of angle x. angle x = I

Furkat [3]

If one Angle is = 30

And the other two angles are equal

Given: x = l

ATQ

⇒30+x+l= 180

⇒x + x = 180-30

⇒2x = 150

⇒x = 150/2

⇒x = 75

Therefore x = 75

And the angles are 30, 75 and 75
