Answer:
see below
Step-by-step explanation:
The sum of the interior angles is 180
<1 + <2 + <4 = 180
<1 + 31+ <4 = 180
<1 + <4 = 180-31
<1 + <4 = 149
<2 + <3 = 180 because it forms a straight line
31 + <3 = 180
<3 = 180-31
<3 = 149
Setting theses equal (since they are both equal to 149)
<1 + <4 = <3
The exterior angle is equal to the sum of the opposite interior angles
15 / 330 = 20 / x...15 gal. to 330 miles = 20 gal to x miles
cross multiply because this is a proportion
(15)(x) = (20)(330)
15x = 6600
x = 6600/15
x = 440 <=== 20 gallons will take u 440 miles
Answer:
120
Step-by-step explanation:
All the angles should add up to equal 180 so,
28 + 32 + ? = 180
60 + ? = 180
180 - 60 = 120
