Step-by-step explanation:
hope this helps u
(2x+40)+(3x+20)=180
because they are supplementary angles
therefore:
2x+3x+40+20=180
5x+60=180
5x=120
x=24
Answer:
m<ADB=70°
m<ADC=110°
m<DAC=45°
Step-by-step explanation:
<ADB=<ABD(being isosceles triangle: AD=AB)
<ABD+<ADB+<DAB=180°(sum of the angle of triangle is 180°)
2<ADB+40°=180°(<ADB=<ABD and <DAB=40°)
2<ADB=140°
<ADB=70°
<ADB+<ADC=180°(being straight angle)
70°+<ADC=180°
<ADC=110°
<ADC+<ACD+<DAC=180°( sum of the angle of triangle is 180°)
110°+25°+<DAC=180°
<DAC=45°
