Answer:
Therefore the measure of the missing angle x, is 90°.
Step-by-step explanation:
Let name the vertices of a Quadrilateral as ABCD such that
∠A = 107°
∠B = 72°
∠C = 91°
∠D = x
To Find:
x = ?
Solution:
In a quadrilateral,
Sum of the measures of all the angles is add up to 360°
![\angle A+\angle B+\angle C+\angle D=360\°](https://tex.z-dn.net/?f=%5Cangle%20A%2B%5Cangle%20B%2B%5Cangle%20C%2B%5Cangle%20D%3D360%5C%C2%B0)
Substituting the values we get
![107+72+91+ x = 360\\x = 360 -270=90\\\therefore x=90\°](https://tex.z-dn.net/?f=107%2B72%2B91%2B%20x%20%3D%20360%5C%5Cx%20%3D%20360%20-270%3D90%5C%5C%5Ctherefore%20x%3D90%5C%C2%B0)
Therefore the measure of the missing angle x, is 90°.
Answer:
-6-4i
Step-by-step explanation:
-2-4-4i. is. ^^
Step-by-step explanation:
C
Step-by-step explanation:
This has a U like shape so it a parabola.
Parabola correlate with quadratic functions
![y = {ax}^{2} + bx + c](https://tex.z-dn.net/?f=y%20%3D%20%20%7Bax%7D%5E%7B2%7D%20%20%2B%20bx%20%2B%20c)
Since it Going down, the answer is C -x^2.
