Answer:

26°

Step-by-step explanation:

AC=tan 64

BC=x=sec 64

Using sine rule

(Sin 64)/tan 64 = (sin BAC)/sec 64

Cos 64 = (sin BAC)(cos 64)

Sin BAC= 1

BAC=90

ACB+ 64+90=180

ACB= 26°

Putting the values of consecutive sides equal:

So, KI will be equal to LI

3x-7 = x+3

$3x-7-x=x+3-x\\2x-7=3\\2x-7+7=3+7\\2x=10\\x=5$

Putting the value of x in the equation of KI

3x-7

=3(5)-7

=15-7

Hence, the correct answer is D. 8 ..
