Plz i need help walk me through it, thanks​
SVETLANKA909090 [29]

Answer:

p=36^{\circ}

Step-by-step explanation:

We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is 90^{\circ}.

Because all the angles of a triangle sum to 180^{\circ}, we have that p+54+90=180.

We combine like terms on the left side to get p+144=180.

We subtract 144 on both sides to get p=36.

So, \boxed{p=36^{\circ}} and we're done!

If two dice are thrown whats si the probability that they will add to 9?A2/36B3/36C3/36D4/36
GuDViN [60]

Answer:

D.\frac{4}{36}

Step-by-step explanation:

Solution,

Two dice are thrown.

So we have to find out the total number of outcomes.

(1,1),\ (1,2),\ (1,3),\ (1,4),\ (1,5),\ (1,6)

(2,1),\ (2,2),\ (2,3),\ (2,4),\ (2,5),\ (2,6)

(3,1),\ (3,2),\ (3,3),\ (3,4),\ (3,5),\ (3,6)

(4,1),\ (4,2),\ (4,3),\ (4,4),\ (4,5),\ (4,6)

(5,1),\ (5,2),\ (5,3),\ (5,4),\ (5,5),\ (5,6)

(6,1),\ (6,2),\ (6,3),\ (6,4),\ (6,5),\ (6,6)

The total number of outcomes = 36

We have to find out the probability of outcomes that add up to 9.

So, Possible outcomes are;

<u>(3,6),\ (4,5),\ (5,4),\ (6,3)</u>

The total number of possible outcomes = 4

Now, according to the formula of probability,

P(E)=\frac{Total\ number\ of\ Possible\ outcomes}{Total\ Number\ of\ outcomes}

P(of\ add\ up\ to\ 9)=\frac{4}{36}

Hence the correct option is D)4/36.
