Answer:
9°, 9°, 162°
Step-by-step explanation:
Let x represent the measure of the first angle. Then the sum of all of the angles in the triangle is ...
x + x + 9(x+x) = 180°
20x = 180° . . . . . . . . . . collect terms
x = 180°/20 = 9° . . . . . divide by 20
9(x+x) = 162° . . . . . . . find the third angle
The three angle measures are 9°, 9°, and 162°.
<span>Solving for y
</span>
y - 5 = 3(x - 1)<span>
Add 5 to both sides
</span>y - 5 + 5 = 3x - 3 + 5
y = 3x + 2
Your answer: y = 3x + 2<span>
