Answer:
m∠ABC=42°
Step-by-step explanation:
m∠ABD=70°
⇒m∠ABD=m∠ABC+m∠CBD
⇒70°=(3x+33°)+(5x+13°)
70°=8x+46°
70°-46°=8x
24°=8x⇒x=3°
x=3°
Then,
m∠ABC=3x+33°
put x=3°, we get
m∠ABC=3×3°+33°=9°+33°
m∠ABC=42°
Hello,
The length of the line segment is the distance betheen the 2 points
d²=(3-6)²+(1-6)²=9+25=34 (pythagorean theorem)
d=√34
$60 , because 20%=10%+10%, and 75 10%=7.5, 7.5+7.5=15, so 75-15=60
