A quadrilateral has 4 vertices and the sum of the measures of the interior angles is 360 degrees. There cannot be 4 diagonals in a quadrilateral.
Answer: 145.8
Step-by-step explanation: you have to divide 45 and 25 to get 1.8, then you get 81 and you multiply 81 x 1.8 to get your answer.
If you do the distance formula you get 13 as the answer.
Answer:
The size is 37.5 degrees
Step-by-step explanation:
The total angle in the triangle is 180
Since the other two angles are congruent. it means that they are equal
Let us call each of the angles x
Mathematically,
x + x + 105 = 180
2x = 180-105
2x = 75
x = 75/2
x = 37.5
