Step-by-step explanation:
do you that is responsible for that another is probability
Answer is A. 20.25
cause 20.25 x 9 = 81
√81 = 9
so 9 is the geometric mean <span>between 4 and 20.25</span>
Break the figure into a triangle and a rectangle.
The triangle has a base of 6 and a height of 3, so the area is 6*3/2 = 18/2 = 9
The rectangle has a length of 5 and a height of 6, so 6*5 = 30 is the area of the rectangle.
The total area is 30+9 = 39
Answer: 39
Answer:
1 Angle A is 44, 2 angle A is 20.
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Equation for 1 is x + 45 + 82 + x + 65 = 180 x = -1 A = 44 Degrees
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Equation for 2 is x + 21 + 130 + x + 31 = 180 x = -1 Angle A = 20 Degree

Answer:
Option C) 144 centimeters squared.
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The surface area of a prism is equal to
where
B is the area of the base of the prism
P is the perimeter of the base
L is the length or height of the prism
<em>Find the area of the base B</em>
---> the base is a right triangle
<em>Find the perimeter of the base P</em>
---> is the perimeter of a triangle
we have
Find the surface area SA
