Answer:

Assuming that the figure is a rectangle:

x=12

angle GJH=22 degrees

Step-by-step explanation:

angle GHJ=angle IJH

5x+8=7x-16

simplify

2x=24

x=12

angle IJH=7x-16

substituting for x

IJH=7(12)-16=84-16=68 degrees

angle GJH=90-IJH

angle GJH=22 degrees

<u>ANSWER</u>=<u>5.2</u>

<u />

<u>EXPLANATION</u>

This triangle shows a example of the Pythagorean Theorem, which means the equation is gonna be

a^2+b^2=c^2

The variables <u>a </u>and <u>b </u>are the straight sides of the triangle, while the variable <u>c </u> is the curved side on the triangle, or what we are trying to find in this question.

Firstly let’s take the two sides that already have a number shown, also known in the Pythagorean Theorem as sides <u>a </u>and <u>b</u>.

2^2+4.8^2=c^2

Now we want to square the two given numbers to get the equation

4+23.04=c^2

Now we add the two given numbers that we have now squared to get the equation

27.04=c^2

The final step will now be to take the number (27.04) and square root it, which should give you the answer, <u>5.2</u>
