Log 3 pi by 2 equal to log 10 Q by 4 equal to log 10 by 8 equal to K and pqr equal 200 find ke​

Answer»

Answer:

In △ABC AB=AC

⇒∠B=∠C (Angles OPPOSITE to equal sides are equal)

Now USING angle sum property

∠A+∠B+∠C=180

⇒80

+∠C+∠C=180

⇒2∠C=180

−80

⇒∠C=

2

100

=50

now ∠C+∠x=180

(Angles made on straight line (AC) are supplementary)

⇒50

+∠x=180

⇒∠x=180

−50

=130
