Answer:
139 degrees
Step-by-step explanation:
we only have a central angle here (angle at the center of the circle).
and that angle remains the same along these 2 lines all the way out to the circle arc (and beyond, wherever these 2 lines take us).
so, if there is nothing missing in this graph, then x is the same as the inner angle : 139 degrees
Answer:
Center ( 4 , -2) and r = 6
Step-by-step explanation:
x² - 8x + y² + 4y - 16 = 0
x² - 8x + y² + 4 y = 16
x²- 2*4x + y² + 2 *2y = 16
(x² - 2*4x + 16 ) - 16 + (y² + 2*2y + 4) -4 = 16
(x - 4)² + (y + 2)² = 16 + 16 + 4
(x - 4)² + (y -[-2])² = 36
(x- 4)² + ( y - [-2] )² = 6²
Compare with (x - h)²+ (y - k)² = r²
Center ( 4 , -2) and r = 6
1. ([4.5*8]-4.5x)+36=102+([-2.5*3x]+[24*-2.5])
2. 36-4.5x+36=102-7.5-60
3. -4.5x/-4.5=52.5/-4.5
4. x=-13.125
a: -13.125
Answer:
242
First is 9 times 10 which is 90, then 4 times 8 is 32 divided by 2 which is 16 times 2 since there are two, 32 again. 8 times 10 is 80. 4 times 10 is 40.
90 + 32 + 80 + 40 = 242
