Answer:
8(x+6y)
Step-by-step explanation:
Answer:
84°
Step-by-step explanation:
The central angle of a circle is twice any inscribed angle subtended by the same arc.
because AB is a diameter, we also know that the triangle angle at C is 90° (all the inscribed triangles with their baseline being a diameter are right-angled).
as always, the sum of all angles in a triangle is 180°.
so, we know the triangle angle at A is
180 - 90 - 48 = 42°.
this is also the inscribed angle of the arc BC.
the central angle for arc BC (that is what is requested here) is then twice that angle : 2×42 = 84°
Answer:
<u>x = 10</u>
Step-by-step explanation:
3x + 8y - 36 = 0 ( <em>given</em> )
3x + 8y = 36 ( <em>change sides of 36</em> )
3x + 8 ( 3 / 4) = 36 ( implementing the value of y which is given )
3x - 2 * 3 = 36 ( <em>8 * 3 / 4 = 2 * 3</em>)
3x - 6 = 36
3x = 36 -6
3x = 30
x = 30 / 3
<u> x = 10 </u>
therefore the coordinates will be (10,3/4)
