The interior angles of any convex quadrilateral add up to 360º in measure.
This means angle 1, whose measure is 42.5% of this total, has measure 0.425*360º = 153º.
Similarly, angle 2 has measure 0.075*360º = 27º, and angle 3 has measure 0.175*360º = 63º.
So
153º + 27º + 63º + <em>x</em>º = 360º ==> <em>x</em> = 117
Answer:
48 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
If one angle is 132 degrees, the other must be 48 degrees.
The answer to this question is C. 11. (I am making a joke by mentioning the music disc C418 Music Disc Variation 11 from Minecraft. I hope you play or else you might not get the joke I implied.) Hoped this helped. (Also I am going for 10 Brainliest answers. I would greatly appreciate it if you chose mine as the Brainliest answer. Thank you 100 times in advance. :))
