Answer: it would be C
Step-by-step explanation:
The arc subtends an angle of 300° .
Step-by-step explanation:
Radius = 75 cm
Arc length = 125π cm
Arc length = (θ/360) (2πr)
125π = (θ/360) (2π x 75)
125π = (θ/360) (150π)
125π/150π = (θ/360)
5/6 = (θ/360)
(5/6) (360) = θ
θ = 300°
The arc subtends an angle of 300° .
Answer: Table B is a direct variation.
Step-by-step explanation:
Table A contains data that fits the expression y = x+3. This is not a direct variation. The ratio of x and y is not a constant. Table B matches the expression y = 3x. This is a direct variation. Table C can be expressed as y = x - 3. This is not a direct variation, for the same reason as Table A.
Answer:
x = 5
y = 40°
Step-by-step explanation:
the median and the base of the large triangle are parallel so angle y has the same measure as the one labeled as 40°
the median is half the base of the large triangle, so 5x = 8x + 10/2
cross-multiply: 10x = 8x + 10
2x = 10
x = 5
