Answer: 
<u>Step-by-step explanation:</u>
Pythagorean Theorem is: a² + b² = c² , <em>where "c" is the hypotenuse</em>
<em />

Note: 4² + (8√2)² = hypotenuse² → hypotenuse = 12

Note: 12² + opposite² = 20² → opposite = 16

Note: adjacent² + 5² = 6² → adjacent = √11

Note: adjacent² + 7² = (13√2)² → adjacent = 17
Answer:
<em>a) g(-2) = 0</em>
<em>b) g(-1) =1</em>
<em>c) g(4) = 2</em>
Step-by-step explanation:
Given data



<u><em>Step( i )</em></u>:-

put x = -2

<em>g(-2) = 0</em>
<u><em>Step(ii)</em></u>:-

Put x = -1

<em>g(-1) =1</em>
<u><em>Step(iii)</em></u>:-

<em>g(4) = 2</em>

Since this is a triangle all the angles within the triangle add up to 180 degrees so....
82+(9x+2)+(7x)=180
82+2+16x=180
16x+84=180
16x=96
X=6
If we plug in X to angle(9x+2) and angle (7x) we will get 56 and 42. We can get angle 2 by subtracting 180-42 which is 138
FINAL ANSWER: 138 degrees
