Angle a is 1/3 or angle b and a+b=12. Find a and b.
Answers
Answer:
a=3
b=9
Step-by-step explanation:
Given
a=1/3×b=b/3
a+b=12
b/3+b=12
b/3+3b/3=12
4b=12×3
4b=36
b=36/4
b=9
Substituting b=9 in a+b=12
a+9=12
a=12-9
a=3

Basic Definitions of Geometry
A collinear set of points is a set of points all of which lie on the same straight line.
A noncollinear set of points s a set of three or more points that do not all line on the same straight
line.
A Line has no endpoints.

A B
A Ray has one endpoint.

C D
Line Segment has two endpoints.

Congruent segments are segments that have the same measure.
The Midpoint of a line segment is a point of that line segment that divides the segment into two
congruent segments.
The Bisector of a line segment is any line, or subset of a line that intersects the segment at the
midpoint.
An Angle is a set of points that is the union of two rays having the same endpoint.
