The sum of all 3 angles in a triangle is 180
180-44=136
And you know that angle A is over 90 degrees so I believe it is 100 leaving angle b to be 36
Answer:
78.5 cm^2
Step-by-step explanation:
The area of a circle is found by
A = pi r^2
A = pi (5)^2
A = 25pi
Letting pi = 3.14
A = 25(3.14)
A =78.5 cm^2
Letting pi be the pi button
A =78.53981634
Rounding to the nearest tenth
78.5
The ranges are 14, 4, and -21

Hello!
You find the area of all three shapes and add them together
We can do the one on the left first
To find the area we multiply the sides
8 * 7 = 56
The one on the left has an area of 56 ft squared
Now lets do the one on the right
8 * 7 = 56
The one on the left has an area of 56 ft squared as well
Finally lets do the one in the middle
We first have to find the length
8 + 12 = 20
Now we multiply
20 * 20 = 400
The middle one has an area of 400ft squared
Now we add them together
56 + 56 + 400 = 512
The answer is 512ft squared
Hope this helps!
