Find the length of segment C as well as m∠A and m∠B. Write your answer rounded to the nearest tenth.

Step-by-step explanation:

Given

See attachment

Solving (a): Segment C

To do this, we make use of Pythagoras theorem

Take the square root of both sides

--- Approximate

Solving (b): Measure of A

To do this, we make use of:

This gives:

Take arcsin of both sides

Solving (c): The measure of C

This is calculated as:

So, we have:

two data sets with the same median will not have the same varaibility

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
