Answer:
(3)》》》60°
Step-by-step explanation:
Since the exterior angle of a triangle is
equal to the sum of non-adjacent interior angles, we have
<DAB=<ABC +<BCA
》180-3x =(6x-40) + (x+20)
》180-31 - 3t sx-not x+20
》180-3x - 72-20
》7x+3x= 180+20
》10x=200
》x=20°
(Being complementory angles)
<DAB+ <BAC = 180°
》180-3×20°+<BAC=180
》<BAC=60°

Answer:
<em>The actual distance between the two towns is 105 km</em>
Step-by-step explanation:
<em>Lets use a proportion for this scenario</em>
<em>1/30 = 3.5/?</em>
<em>We see that the numerator is multiplied by 3.5, from 1 to 3.5</em>
<em>So we do the same to the denominator</em>
30 x 3.5 is 105 km
So your answer is 105 km
