Ray CE is the angle bisector of ACD. Which statement about the figure must be true?

Viefleur [7K]

we know that

"Bisect" means to divide into two equal parts

If the ray CE is the angle bisector of ADC

then

$Angle(ACD)=Angle(ACE)+Angle(ECD)$

$Angle(ACE)=Angle(ECD)$

$Angle(ACD)=2Angle(ACE)$

$Angle(ACE)=\frac{1}{2} Angle(ACD)$

therefore

<u>the answer is the option</u>

$Angle(ACE)=\frac{1}{2} Angle(ACD)$

$Angle(ACE)=Angle(ECD)$

The water level of a river is 170 feet. The river recedes 4 feet each year. Ingrid claims that the equation that represents this

Vladimir [108]

Sample Answer: No, Ingrid is incorrect. The initial value in the scenario is 170 feet, which represents the y − intercept. Receding 4 feet in the scenario represents the rate of change, which is the slope. In slope-intercept form, y = mx + b, where m represents slope and b represents the y−intercept, so the correct equation is y = −4x + 170.
