A Pentagon can be broken up into 5 equal triangles. Area of the Pentagon is the sum of all the 5 triangles.
Area of the pentagon = 5 ( 1/2 x 6.2 x 9) = 139.5 mm²
Answer: 129.5 mm² (Answer D)
Answer:
Step-by-step explanation:
Let the number is in the form of xyz
<h3>We have</h3>
Sum of the digits is 19
The second digit is one more than the first digit
The third digit is two more than the second digit
- z = y + 2 = x + 1 + 2 = x + 3
<u>Substitute the values of y and z</u> into the first equation and solve for x
- x + x + 1 + x + 3 = 19
- 3x + 4 = 19
- 3x = 15
- x = 5
<u>Find the value of y and z</u>
- y = 5 + 1 = 6
- z = 5 + 3 = 8
The number is 568
Answer:
angle 5 is 61°
angle 7 is 61°
Step-by-step explanation:
1. angle 7 + angle 8 = 90° Because they are complementary angles
2. Because of point 1 above, angle 5 + angle 6 = 90°
3. since given angle 6 = 29°
so, angle 5 = 90° - 29° = 61°
4. since given angle 5 = angle 8
so, angle 8 = 61°
5. from point 1 above,
angle 7 + 61° = 90°
so angle 7 = 29°
Answer:
Rational
Step-by-step explanation:
The definition of rational is that it can be written as a fraction where the top and bottom are integers (the bottom integer not 0).
--
43/10 is written in that form since 43 and 10 are both integers.
