ΔJKL, sin(JLK)=JK/KL=3/6=0.5
<JKL=30deg.

cos(JLK)=JL/KL
JL=KL*cos(JLK)=6cos(30deg.)

<JLK + <JLM = <MLK
30 + <JLM = 61
<JLM=31deg

in ΔMJL
tan(JLM)=JM/JL
JM=JL*tan(JLM)
=6cos(30deg.)*tan(31deg)
=3.12

TiliK225 [7]

Answer:

The length of CI is 10 units.

Step-by-step explanation:

It is given that ABCD is a parallelogram and diagonals AC and BD intersect at point I.

The diagonals of a parallelogram bisect each other.

AI=CI

AC=AI+CI

AC=AI+AI                 [\because AI=CI]

AC=2AI

3x-16=2(x-2)

3x-16=2x-4

3x-2x=16-4

x=12

The value of x is 12.

CI=AI=x-2=12-2=10

Therefore the  length of CI is 10 units.

A 52-in TV measures 52 inches along its diagonal (corner to corner measure). If that TV is 33.6 inches high, how wide is it?
Zinaida [17]

Step-by-step explanation:

Use Pythagoras' theorem

{a}^{2}   =  b {}^{2}  + c {}^{2}

52² = 33.6² + x²

solve for x
