The answer of the question is in the picture.
X = 80
Answer:
0.3*10+10/5
PEMDAS (left to right)
3+2
5
Step-by-step explanation:
The centroid is the average of the three vertices’ coordinates, so it’s ((-1+1+5)/3, (3–1+1)/3) or (5/3, 1).
Based on the triangle sum theorem and the triangle inequality theorem:
1. B. 23°, 67°, 90°.
2. A. 1 cm, 2 cm, 3 cm.
<h3>What is the Triangle Sum Theorem?</h3>
According to the triangle sum theorem, all three interior angles of any triangle has a sum of 180 degrees.
What is the Triangle Inequality Theorem?
Based on the triangle inequality theorem, one side of a triangle must be less than or equals the sum of any other two sides of the triangle. (a + b ≥ c).
Part 1:
23° + 67° + 90° = 180°, therefore, based on the triangle sum theorem, the set of angle measures that could be the interior angles of a triangle is: B. 23°, 67°, 90°.
Part 2:
1 + 2 = 3
1 + 3 > 2
2 + 3 > 1
Therefore, based on the triangle inequality theorem, the set of side lengths that could be that of the sides of a triangle is: A. 1 cm, 2 cm, 3 cm.

Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
<h3>
</h3>
To solve for y cross multiply
That's
3( x - 1) = 2y
2y = 3x - 3
Divide both sides by 2 to make y stand alone
That's
<h3>
</h3>
We have the final answer as
<h3>
</h3>
