Answer:
hello,
answer C
Step-by-step explanation:
area of the rectangle=2b*b=2b²
area of the half cercle= ![\\\dfrac{\pi*(\frac{c}{2})^2}{2} =\dfrac{\pi*c^2}{8} \\](https://tex.z-dn.net/?f=%5C%5C%5Cdfrac%7B%5Cpi%2A%28%5Cfrac%7Bc%7D%7B2%7D%29%5E2%7D%7B2%7D%20%3D%5Cdfrac%7B%5Cpi%2Ac%5E2%7D%7B8%7D%20%5C%5C)
Area in blue= 2b²-πc²/8
Answer:
a = 49°
Explanation:
You use the rule ‘exterior angle of a triangle’ which states that the exterior angle is equal to the sum of the two opposite interior angles.
To put it mathematically:
a + a = a + 49° (Ext angles of triangle)
a = a - a + 49°
a = 49°
Answer:
The answer is -18
Step-by-step explanation:
Actually if the x2 is supposed to be x^2 then it's -10
