Given:

A figure of a right angle triangle.

To find:

The value of Tan R.

Solution:

Trigonometric Ratio: In a right angle triangle,

\tan \theta =\dfrac{Perpendicular}{Base}

Using the above trigonometric ratio in the given triangle, we get

Tan R =\dfrac{AD}{AR}

Tan R =\dfrac{13}{17}

Therefore, the correct option is C.

X+3y-2z=10, -x-2y+z=-7, 3x+9y-5z=28
NISA [10]
Hmm
what you do is try to eliminate 1 variable in 2 equaions first
we can elminate x's in first and 2nd equation

add first and 2nd equation
x+3y-2z=10
<u>-x-2y+z=-7 +</u>
0x+y-z=3
y-z=3


multiply 2nd equation by 3 and add to last one
-3x-6y+3z=-21
<u>3x+9y-5z=28 +</u>
0x+3y-2z=7

3y-2z=7

we now have
y-z=3
3y-2z=7
multiply first equation by -2 and add to 2nd

-2y+2z=-6
<u>3y-2z=7 +</u>
y+0z=1
y=1

now we can sub back
y-z=3
1-z=3
minus 1
-z=2
times -1
z=-2

sub baack into any equation
x+3(1)-2(-2)=10
x+3+4=10
x+7=10
minus 7
x=3

x=3
y=1
z=-2
(3,1,-2)
