Answer:
Angle OAB = 90°
Reason: tangent theorem of a circle
Step-by-step explanation:
The diagram given shows a tangent line of the given circle with center O. The tangent touches the circle at point A.
The diagram also shows the radius of the circle, OA, drawn from the center to the circle to meet at the point of tangency.
Thus, according to the Tangent Theorem of a circle, the point at which the radius drawn from the center meets the point of tangency = 90°. The tangent is perdendicular to the radius drawn to meet at the point of tangency.
Therefore, angle OAB = 90°
Answer:
6%
Step-by-step explanation:
60 = 500•2•rate
60 = 1000•rate
rate = 60/1000
rate = 0.06 = 6%
2(11)+2x=38
22+2x=38
2x=38-22
2x=16
x=16/2
x=8
The width of the rectangle is 8 feet.
12x+15y=34
2(-6X+5Y)=3
12x+15y=34
-12x+10y=6 = 25y=40 25/40 =0.25 then you plug that back into any original equation and you get the x
