Answer:
The measure of the smallest angle is 30º
Step-by-step explanation:
Let the angles be:
the first angle (the smallest)
the second angle
the third angle
So, we have:
Required
Find x
The angles in a triangle is:
Substitute values for y and z
Collect like terms
Divide by 4
C) 5x-70=105
As marked in the graph, angle 105 and angle (5x-70) equal to each other because they are vertically opposite angles therefore we have equation C)
