So if you're trying to find the other section of the 128 degree angle that isn't taken up by the 33 degree angle, or LHI, you just subtract 33 from 128. This is because you need to find the angle GHI without the part GHL, so just subtract that part away.

128 - 33 = 95

So therefore angle LHI is equal to 95.

Answer:

Step-by-step explanation:

Given

<LON = 77°

<LOM = (9x+44)°

<MON = (6x+3)°

The addition postulate is true for the given angles since tey have a common point O:

<LON = <LOM+<MON

Since we are not told what to find we can as well look for the value of x, <LOM and <MON

Substitute the given parameters and get x

77 = 9x+44+6x+3

77 = 15x+47

77-47 = 15x

30 = 15x

x = 30/15

x = 2

Get <LOM:

<LOM = 9x+44

<LOM = 9(2)+44

<LOM = 18+44

<LOM = 62°

Get <MON:

<MON = 6x+3

<MON = 6(2)+3

<MON = 12+3

<MON = 15°

The grid shows figure Q and its image figure Q’ after a transformation. Which transformation was applied on figure Q?

photoshop1234 [79]

Answer:

B.) Clockwise rotation of 90° about the origin.

Step-by-step explanation:

We see that the co-ordinates of the figure Q are (2,4), (3,7), (7,5), (5,4) and (4,2).

It can be seen that the co-ordinates changed after the transformation are (4,-2), (7,-3), (5,-7), (4,-5) and (2,-4).

That is,

Q Q'

(2,4) ---------------------> (4,-2)

(3,7) ----------------------> (7,-3)

(7,5) ----------------------> (5,-7)

(5,4) ----------------------> (4,-5)

(4,2) ----------------------> (2,-4)

Thus, the co-ordinates are changing by the rule (x,y) → (y,-x).

Hence, the transformation applied is 'Clockwise rotation of 90° about the origin'.

So, option B is correct.

The graph is not a straight line, it is curved. You can observe this only if you include the point (1,0), which is the level at the begining (100%)

The y - intercept is the full level, at the beginning of the experiment.
