Question

question 19
kl = _
a) 2
b) 6
c) 20
question 20
hi = _
a) 4
b) 5
c) 14

Explanation:

Step1: Analyze Question 19

Let $IL = 26$, $IJ=9$, $JK = 11$. We know that $IL=IJ + JK+KL$. So, $KL=IL-(IJ + JK)$.

Step2: Calculate $KL$

$KL=26-(9 + 11)=26 - 20=6$.

Step3: Analyze Question 20

Let $GJ=7 + 12=19$, $GH = 2$, $HI=x$, $IJ = 12$, and $GJ=GH+HI+IJ$. So, $HI=GJ-(GH + IJ)$.

Step4: Calculate $HI$

$HI=19-(2 + 12)=19 - 14 = 5$.

Answer:

Question 19: B. 6
Question 20: B. 5
