Answer:
See below
Step-by-step explanation:
SAS requires two sides and the included angle to be congruent
Steve needs to measure sides EK and AC and if they are congruent, he can then complete his proof
<u>Let's find the measure of EK and AC</u>
- EC =

- AC =

As we see EK = AC = 10, so the proof is complete
Part A: The answer is PR = 15.23 by Pythagorean Theorem.
The pythagorean theorem is a^2 + b^2 = c^2.
Plug in 14 for a and 6 for b to find c.
Part B: The answer is QR = 7.75.
Using the same theorem, plug 16 in for c, 14 in for a, and then you can find b.
False
because tan^2 45 = 1^2 = 1
and sec^2 x = 1/ cos^2 45 = (sqrt2)^2 = 2
so the sum = 3
