30°, 70°, and 80°.
It is an acute-angled triangle.
Explanation:
The ratio of the measures of ∠s in Δ is 3:7:8.
So, let us suppose that the measures are, 3k, 7k, 8k.
Evidently, their sum is
180°.
3k+7k+8k=180
18k=180
k= 10
Hence, the measures are,
30°, 70°, and 80°.
As all the angles are acute, so is the triangle.
Answer: Its the first choice
Step-by-step explanation:
Answer:
189282
Step-by-step explanation:
Corresponding angles are defined as angles that are on the same side of the transversal (given the lines are parallel, which they are) and are on the same side of the parallel lines. Choices D, E, and F are angles on the same side of the transversal and on the same side of the parallel lines.
