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.
Be more specific on the first one
A right angle is 90 degrees
So you 90/4=22.5
Then 90+22.5=112.5
Hope this helped!
Because it says it’s looking for the ESTIMATED sum. Round your answer to the nearest tenth, and that would be an estimated answer.
