Find the measure of the arc or angle indicated.

xenn [34]

For each problem, use the inscribed angle theorem.

19.

$45^\circ=\dfrac12m\widehat{QR}\implies m\widehat{QR}=90^\circ$

20.

$95^\circ=\dfrac12m\widehat{ABC}\implies m\widehat{ABC}=190^\circ$

21.

$49^\circ=\dfrac12m\widehat{LR}\implies m\widehat{LR}=98^\circ$

LN is a diameter, so arc LN has measure 180º, and so

$m\widehat{LR}+m\widehat{RN}=m\widehat{LN}=180^\circ\implies m\widehat{RN}=82^\circ$

Simplify<br><br> 14 +{ -2 + 3 [ 1 +3 ( -6 -2 ) ] }

gregori [183]

ANSWER: -57
14+{−2+3[1+3(−6−2)]}
= 14+{−2+3[1+3(-8)]}
= 14+{−2+3[1+(-24)]}
= 14+{−2+3[1-24]}
= 14+{−2+3[-23]}
= 14+{−2+[-69]}
= 14+{−2-69}
= 14+(-71)
= 14 - 71
= -57

Please answer as fast as possible thanks

svp [43]

The correct answer is the 2nd choice because -1/6 is closer to 0 and the surface of the pool would be considered 0. -4/6 is farther away from 0 so it is less.
