Question

3) Sketch the proper figure write the answers of the following questions.

a) If A – B – C and l(AC) = 17, l(BC) = 10.5 then l(AB) = ?

b) If X – Y – Z and l(XZ) = 4√ , l(XY) = √ then l(YZ) = ?​

Answer 1

Answer:

we have,

L(Ac)=17

l(Bc)=10.5

Step-by-step explanation:

so,

l(ac)=l(ab)+l(bc)

17. = l(ab) + 10.5

17-10.5=l(ab)

6.5 = l(ab)

therefore l(ab)= 6.5
