Given:
The measurement of the angles of a triangle are 3b,2b,and 4b.
To find:
The smallest angle.
Solution:
According to the angle sum property, the sum of all angles of a triangle is 180 degrees.
[Angle sum property]

Divide both sides by 9.

Now,



Therefore, the smallest angle is 40 degrees.
Answer:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

hope this helps if do mark brainllest pls
Answer:
8xy
Step-by-step explanation:
Subtract -13xy from -5xy
-5xy - (-13xy) =
-5xy + 13xy =
8xy
<em>good luck, i hope this helps:)</em>
its (a) because (a) is C(x)=3x4+30x and 9+21 is 30 so its 3x2+30
