Answer: Choice A) Triangle ABC is similar to triangle ACD by AA

AA stands for Angle Angle. Specifically it means we need 2 pairs of congruent angles between the two triangles in order to prove the triangles similar. Your book might write "AA similarity" instead of simply "AA".

For triangles ABC and ACD, we have the first pair of angles being A = A (angle A shows up twice each in the first slot). The second pair of congruent angles would be the right angles for triangle ABC and ACD, which are angles C and D respectively.

We can't use AAS because we don't know any information about the sides of the triangle.

What is the area of a triangle that has a base of 15 1/4 in. And a height of 18 in.

Minchanka [31]

Answer:

144

Step-by-step explanation:

Use the triangle formula base times height times 1/2 (1/2xbxh) so 15.25 (15 1/4) times 18 = 288. Then you can divide 288 by 2 or multiply it by 1/2 you get the same answer regardless which the final answer is 144.

If the distance between the points<br>(4.p) and (1,0) is 5, then p=? *

Hatshy [7]

Answer:

p=4

Step-by-step explanation:

distance b/n points is given by formula

$5= \sqrt{(1 - 4{}) {}^{2} + (0 - p {}^) {}^{2} }$

$25 = {9 + p {}^{2} }$

$p {}^{2} = 25 - 9$

$p = 4$

Use the FOIL method to find the product below. (x + 5)(x2 – 3x)

Svetllana [295]

(x + 5)(x² - 3x)

Use FOIL (First, Outside, Inside, Last)

x(x²) = x³
x(-3x) = -3x²
5(x²) = 5x²
5(-3x) = -15x

Combine like terms:

x³ - 3x² + 5x² - 15x

x³ + 2x² - 15

x³ + 2x² - 15 is your answer

hope this helps

1. What value of x makes the equation 6x - 14+ 3(2x - 1) = 5 - 2(x - 10) true?

earnstyle [38]

yeet this is a thicc problem...

6x - 14 + 3(2x-1) = 5 - 2(x-10)

first expand

6x - 14 + 6x -3 = 5 -2x-20

now put constants and variables on either sides of the thingamajig

6x+6x+2x= 5 - 20 + 3 + 14

14x = 2

x = 1/7

i deserve an award for that XD
