10
Step-by-step explanation:
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.
When you add all of the totals together your total amount will be $35.875
Answer:
A
Step-by-step explanation:
Given
5(x - 7) = 55, then using the distributive property, that is
a(b - c) = ab - ac, then
5x - 35 = 55
Cross multiply
5/8 and 8/10
5x8=40
8x8=64
40 does not equal 64 so not proportional
