What additional information is required to prove the triangles are congruent using ASA?
Since vertical angles are congruent assume:

Answers

Answer:

C

Step-by-step explanation:

We already have one angle form the question that leaves us with one other angle and one side that we need to find, since we are required to use ASA or angle-side-angle.

the diagram gives us 2 congruent sides UB and AB since they have a similar slash on both of them, finally we need one more angle, so we look at the choices we have:

a) it gives us congruent sides not angles, so we move to the next

b) same thing as A

c) gives us 2 congruent angles, and since these are 2 new angles not given in the question, they can work

d) these 2 angels are the same 2 given in the question, so we can't use them.

Step-by-step explanation:

The unknown number will be equal to 3 / 5. The correct option is B.

What is an expression?

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 0.9 is the result of finding the product of 2 and 3/4 minus a number.

The unknown number will be calculated as,

( 2 x 3) / 4 - N = 0.9

N = (3 / 2) - ( 9/10)

N = ( 15 - 9 ) / 10

N = 6 / 10

N = 3 / 5

Therefore, the unknown number will be equal to 3 / 5. The correct option is C.

The correct options are given below,

A) 3/40

B) 3/5

C) 33/40

D) 1 1/5
