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.

70/13=5.384615
5.38x13=69.94
Answer:
maria will run 1.75 more miles than her goal
Step-by-step explanation:
If you multiply 2.75 to 7 days you will get 19.25. And if you subtract it by 17.5(because that's her goal) you will get 1.75.
So the answer to this question would be:
Maria will run 1.75 more mile than her goal.
Is this qusioun as of today may 18?
For the given triangle, x = 51°.
Step-by-step explanation:
Step 1:
In the given triangle, the angle is x°. The opposite side has a length of 7 units while the hypotenuse of the triangle measures 9 units. To calculate the value of x, we determine the sin of angle x where we divide the length of the opposite side by the length of the hypotenuse.
sin x° 
Step 2:
The length of the opposite side = 7 units.
The length of the hypotenuse = 9 units.


So x° = 50.986°, rounding this off to the nearest degree we get x = 51°.
