Given:
Radius of a circle = 7.8
Intercepted arc length = 44.
To find:
The angle in radians to the nearest 10th.
Solution:
We know that,
Where, r is the radius of the circle and θ is the central angle in radians.
Substituting the values, we get
Therefore, the angle in radians to the nearest 10th is 5.6.
Since the line is 13 units and 8:5 is 13 parts each proportion is 1 unit. Which means 8 parts and 5 parts are on the line. And 8 plus -4, is 4.
The answer is D (4)
30% decrease.
120-90 = 30
Answer:
the answer is B i think
Step-by-step explanation:
Answer:
Obtuse triangle
Step-by-step explanation:
right triangle:
c² = a² + b²
10² = 3² + 5²
100 = 34 NO!
acute triangle:
c² < a² + b²
10² < 3² + 5²
100 < 34 NO!
Obtuse triangle:
c² > a² + b²
100 > 34 <u>YES</u>
