Answer:

D. ASA

Step-by-step explanation:

ASA (Angle-Side-Angle) is a proof of congruence when two triangles share two angles and the side between them.

Answer:

However, note further that the congruent sides are not included sides of the two relevant angles, in which case it won't be ASA but AAS.

Therefore, the two angles are congruent by the AAS Congruence Theorem and the correct answer is C.

Find (ros)(z).

Nady [450]

Answer:

(r*s) = (x-5)(2x+6) = 2x2 + 6x - 10x - 30 = 2x2 - 4x - 30

(r-s)(x) = x-5 - (2x+6) = x - 5 - 2x - 6 = -x - 11

(r+s)(x) = x - 5 + 2x + 6 = 3x + 1

(r + s)(3) = 3(3) + 1 = 9 + 1 = 10

andrew-mc [135]

Answer:

The total number of students that ate lunch are 300 .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ value}$

As given

There are 4 lunch choices in a school cafeteria: Salad, Pizza, Spaghetti, and Sub Sandwiches.

The percentage of students that chose salad is 15%.

If 45 students chose salad.

Here

Percentage = 15%

Part value = 45

Put in the formula

$15 = \frac{45\times 100}{Total\ value}$

$Total\ value= \frac{4500}{15}$

$Total\ value= 300$

Therefore the total number of students that ate lunch are 300 .

A ladder is placed 10 feet away from a tree. The length of the ladder is 25 feet. Find the height of the tree?

Dimas [21]

Answer:

23ft approx

Step-by-step explanation:

Given data

Distance from tree= 10ft

Length of ladder= 25ft

We can find the height of the tree by applying the Pythagoras theorem

z^2= x^2+y^2

z= The height of the ladder

x= The distance from the tree

y= The height of the tree

25^2= 10^2+ y^2

625=100+y^2

625-100=y^2

525=y^2

y= √525

y= 22.91

Hence the height of the tree is 23ft approx
