Answer:
24.9π
Step-by-step explanation:
Curcle Area=πR^2
A= πR^2 × 140°/360°
A= π×8^2 × 0.389 =~ 78.15
Answer:
-3<n<=5
Step-by-step explanation:
This is because the coloured circle on the number line means that the number is less than or equal to 5
The angles must be acute and all the measured angles must be different.
<h3>What is a triangle?</h3>
This a shape with 3 sides and angke
If in ΔNOP, OP = 7, PN = 13, and NO = 19, then the measure of the angles must be different as well;
Hence the statement that must be true about the angles is that the angles must be acute and all the measured angles must be different. The given triangle must also be a scalene triangle
