21 divided by 2 is 10.5 and if you add 4 to it, it gives you 14.5. there you go
Remote interior angles are the two angles that are not supplementary with the exterior angle of a triangle.
<c and <a are the remote interior angles of <y
<a and <b are the remote interior angles of <d
In a tight triangle, one angle measures 90°. All triangles add up to 180° according to the Triangle Sum Theorem. Using the measure of 50°, we can find the measure of the other angle.
90+50=140
180-140=40
The measure of the other angle is 40.
I hope I helped :)
We have to put values of domain to find range
![\\ \ast\sf\longmapsto D_R=[-1,0,1]](https://tex.z-dn.net/?f=%5C%5C%20%5Cast%5Csf%5Clongmapsto%20D_R%3D%5B-1%2C0%2C1%5D)
Now
![\\ \ast\sf\longmapsto R_R=[-2,1,13]](https://tex.z-dn.net/?f=%5C%5C%20%5Cast%5Csf%5Clongmapsto%20R_R%3D%5B-2%2C1%2C13%5D)
