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.

Explain why 7* 6 x 5 x 4*3*2*1+5 is a composite numbers​
xenn [34]

Answer:

7×6×5×4×3×2×1+5 can be written as  5*[7*6*5*4*3*2*+1] or 5*(1009). So, other than the number and 1, it has 5 and 1009 as its factors too. So it is  a composite number.

Step-by-step explanation:

A composite number is a positive integer that has a factor other than 1 and itself.

aivan3 [116]

The value of the expression will be equal to 145.

<h3>What is an expression?</h3>

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that make an expression for divide 50 by half and add 20 and multiply by 2.

The expression will be solved as below,

E = 50/2 + 25 x 2 + 50 + 20

Solve the above expression by PEMDAS,

E = 25 + 50 + 70

E = 145
