The measures of all of the interior angles of the triangle are 70 degrees, 70 degrees and 40 degrees
<em><u>Solution:</u></em>
Given that exterior angle of triangle is 140 degrees
The exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles
Given that adjacent angles are congruent
Let one of the non adjacent interior angles be "x"
x + x = 140
2x = 140
x = 70
So the two interior angles are 70 degrees and 70 degrees
Let us find the third interior angle
The angle sum property of a triangle states that the interior angles of a triangle always add up to 180 degrees
70 + 70 + third angle = 180
third angle = 180 - 70 - 70
third angle = 180 - 140
third angle = 40 degrees
Thus the measures of all of the interior angles of the triangle are 70 degrees, 70 degrees and 40 degrees
The first one is 34 the second one is 392 and the third one is 18
Answer:
Step-by-step explanation:
First add the shoes and the toys: 63+54 = $117
Second subtract 45 dollars from $117 = 72
Third divide 72 by 9 = 8 weeks
Answer: 8 weeks
Answer:
18
Step-by-step explanation:
have a good day :)))))))
None becauase 1 meter is 3 feet so 2 meters is equal to 6 feet.
