Answer:
Step-by-step explanation:
If there are twelve contestants, the number of ways in which they can select the first and second turn can be calculated using the rule of multiplication as:
<u> 12 </u>*<u> 11 </u>= 132
1st turn 2nd turn
Because, they are going to have 12 contestants for the first turn and then they are going to have 11 contestants for the second.
On the other hand, 1 of these options is that you go first and your friend goes second, so the probability that this happens is equal to:
1) last number times 4 and subtract 1
2) last number times2 and add 2
3) you figure out
I think it might be 11x-8
I'm really sorry if that's wrong
Answer:
<A = 116°
<B = 64°
<C = <D = 90°
Step-by-step explanation:
In an inscribed quadrilateral, The sum of opposite angles is equal to 180°
If <A and <B are and also <C and <D opposite angles then:
<A+<B = 180° and
<C+<D = 180°
If <C = <D, then
<C+<C = 180°
2<C = 180°
<C = 180°/2
<C = 90° and <D = 90°
If <A = 9x+17 and <B = 8x-24, then;
9x+17+8x-24 = 180
17x-7 = 180
17x = 187
x = 187/17
x = 11°
<A = 9(11)+17
<A = 99+17
<A = 116°
<B = 180°-116°
<B = 64°
