Answer:

124°

Step-by-step explanation:

This is an Isosceles triangle so the measure of the neighbouring corner to x is

(180 - 76) ÷ 2 = 56

Since x + 56 would be 180 the value of x is 180 - 56 = 124

mars1129 [50]

Answer:

6.37%

Step-by-step explanation:

A deck of cards have 52 cards. There are 4 suits of 13 card each, those suits are Hearts, Clubs, Diamond and Spades.

The probability that the first card is a heart is:

$P(Hearts) = \frac{13}{52}$

Now, the probabily that the second card is a diamond is:

$P(Diamond | First card is Heart) = \frac{13}{51}$

The Probability that the first card is a heart and the second one a diamond is given by:

$P(Hearts)$ × $P(Diamond | First card is Heart)$

$= \frac{13}{52}\frac{13}{51}$

$= 6.37$ %
