Answer:
b. 50
Step-by-step explanation:
The sum of the interior angles of a quadrilateral is 360°, so the missing angle is ...
360° - 110° -40° -80° = 130°
The angle x° is the supplement to this, so is ...
180° -130° = x° = 50°
The value of x is 50.
So I have the same Prb I did 45 and I did incorrect so what I know. 45 it’s incorrect
Should be 2.7 ! i got the answer by multiplying 0.27 by 10 to reset the equation kinda
Answer: The answer is B

Answer:
Step-by-step explanation:
Given two congruent, isosceles triangles are joined, as shown, to form a parallelogram, the largest angle of the parallelogram is 116 degrees. Write two equations. Write them find the value of a and the value of b.
We know that the sum of all the internal angles is 360 degree. So the equation will be
4 a + 2b = 360
According to the question the largest internal angle of the parallelogram is 116 degree. So a + b = 116
Now we have the two equations as
4a + 2b = 360
a + b = 116
Multiply the second equation by 4 we get
4a + 2b = 360
4a + 4b = 464
Or – 2b = - 104
Or b = 52
Now a + b = 116
Or a + 52 = 116
Or a = 116 – 52
Or a = 64
Therefore the values of a and b are 64 and 52 degrees
