pls my answer
will give with explained
no sory
see here As,(hypotenuse)²=(opposite side)²+(adjacent side)²
⇒(17)²=(15)²+(x)²
⇒x²=(17)²-(15)²
⇒x²=289-225
⇒x²=64
⇒x=√64
⇒x=8
Now,CosC=adjacent side/hypotenuse
∴CosC=8/15
⇒(17)²=(15)²+(x)²
⇒x²=(17)²-(15)²
⇒x²=289-225
⇒x²=64
⇒x=√64
⇒x=8
Now,CosC=adjacent side/hypotenuse
∴CosC=8/15
his answer is wrong
its an adjacent side
yes answer is 8
chech my answer ..
pls.mark as brainlist

ANSWER;
Sin the
{15/17}=opposide side/ hypotenuse. Let the adjacent side {be 'x'. }
Let the adjacent side be 'x'
As,(hypotenuse)²=(opposite side)²+(adjacent side)²
⇒(17)²=(15)²+(x)²
⇒x²=(17)²-(15)²
⇒x²=289-225
⇒x²=64
⇒x=√64
⇒x=8
Now,CosC=adjacent side/hypotenuse
∴CosC=8/15
