Given parameters:
Number of sides of the regular body = 10
A decagon has 10 sides.
Unknown:
Sum of the measures of the interior angles = ?
Solution;
To find the sum of the interior angles of a decagon; use the expression below:
Sum of interior angles = (n - 2) x 180
where;
n = number of sides;
So,
Sum of interior angles = (10 - 2) x 180 = 1440°
The sum of interior angle of a decagon is 1440°
Answer:
top: 0.7, 0.9
bottom:7/10
0.7 = 7/10 because 7 is under tens. If it was 0.34 = 34/100 because 34 is in the hundereds. If it was 0.100 = 100/1000 because 100 is under the thousands. pls brainly trying to level up
Answer:
x=4
Step-by-step explanation:
Hence, Height of rectangular prism is 2 feet.
A tangent line is perpendicular to the radius to the point of tangency. Hence QR ⊥ PR. The Pythagorean theorem tells you
(QR)² + (PR)² = (PQ)²
(55 cm)² + (PR)² = (73 cm)²
(PR)² = 2304 cm²
(PR) = √(2304 cm²) = 48 cm
The length of PR is
b. 48 cm
