if the figures shown are congruent what is the value of x? (Hint the sum of three angles of any triangle is 180)

x = 42

Step-by-step explanation:

100 + 38 + x = 180

138 + x = 180

-138 -138

x = 42

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
