Two bikers, Derek and Tina, start riding from the same location. Derek rides due west for x miles. Tina goes due south and cover

kirza4 [7]

Answer: Tina rides 4 miles and Derek rides 3 miles.

Explanation:

Since we have given that

Distance covered by Derek in west direction be x

Distance covered by Tina in south direction be x+1

Distance between the bikers when they both stop is x+2

Since it forms right triangle, so we will apply "Pythagorus theorem":

$H^2=P^2+B^2\\\\(x+2)^2=x^2+(x+1)^2\\\\x^2+4x+4=x^2+x^2+1+2x\\\\x^2+4x+4=2x^2+2x+1\\\\x^2-2x^2+4x-2x+4-1=0\\\\-x^2+2x+3=0\\\\x^2-2x-3=0\\\\x^2-3x+x-3=0\\\\x(x-3)+1(x-3)=0\\\\(x+1)(x-3)=0\\\\x=-1,3$

Since distance can't be in negative sign, so we take x=3 miles

Derek rides 3 miles

Tina rides is given by

$x+1=3+1=4\ miles$

Hence, Tina rides 4 miles and Derek rides 3 miles.

Find Arc measure of ABC

Softa [21]

Answer:

268°

Step-by-step explanation:

$In\: \odot O,$ AB is diameter.

So, $\widehat{AB} \:\&\: \widehat {BA}$ are semicircular arcs.

$\therefore m\widehat {AB} =m\widehat {BA} = 180\degree$

$\because \: m\widehat {BC} = m\widehat {BA} - m\widehat {CA}$

$\therefore \: m\widehat {BC} = (180-92)\degree$

$\therefore \: m\widehat {BC} =88\degree$

$\because m\widehat {ABC} = m\widehat {AB}+m\widehat {BC}$

$\therefore m\widehat {ABC} = 180\degree+88\degree$

$\therefore m\widehat {ABC} = 268\degree$
