Answer:
22.143
Step-by-step explanation:
49.419-27.276=22.143
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
All internal angles in a quadrilateral add to 360
so
x+110+110+70=360
x+290=360
minus 290 both sides
x=70 degrees
Answer:
3/5
Step-by-step explanation:
to see whether the number complete the inequality or not multiple denominator first with 3 you will see it's bigger than 2/3 then with 9 and it is smaller than 7/9.
