Answer: 60cm^2

Explanation:

Since both sides are 13cm it tells us that it is an isosceles triangle.

And we can find the height by using Pythagorean’s theorem.

If we cut the isosceles triangle into 2 same right triangles, we can take one of the right triangle and we can work out the height.

you pick a card at random from an ordinary deck of 52 cards. If the card is an ace, you get 9 points; if not, you lose a point​
nexus9112 [7]

Answer: a = 9, b = 48, c = -1

<u>Step-by-step explanation:</u>

"a" represents the points you receive if an Ace is picked.  It is given that you get 9 points ----> a = 9

"b" represents the number of cards that are Not an Ace.  4 cards in the deck are Aces so 52 - 4 = 48 cards are Not an Ace -----> b = 48

"c" represents the points you receive if Not an Ace is picked.  It is given that you lose 1 point ----> c = -1
