Answer:c
Step-by-step explanation:

The Correct choice is ~ D
The given triangles are not congruent, because they they just have all their corresponding angles equal to one another, so we need more information ~
Answer:

Step-by-step explanation:
To solve for s, you need to follow these steps.
First multiply by t both sides of the equation.


We get 
Now we divide by r, both sides of the equation.

Finallly we obtain:
or

Step-by-step explanation:
let the larger number be x and smaller number be y
according to this question
x=y+33----------(1)
y+33+5y=129----------(2)
6y+33=129
y=16
x=16+33(takimg equation (1)
x=49
To answer this question, use permutation since the order of the letter matters. There are 7 letters and only 4 are to be used for the code. This is a permutation of 7 taken 4 (7P4) which is equal to 840. Thus, the sample space is 840.
For the next questions, there are 3 vowels for as the first letter, only 6 letters are available for the second, 5 on the next, and 4 on the last. Multiplying these numbers give 360. To solve for probability, divide this number with the sample space. Thus, the answer is 3/7.
