Answer:
<h3>B. 16°</h3>Step-by-step explanation:
The diagram lacks the appropriate figure. Find the figure attached. If the line I is perpendicular to m, this means that the sum of the given angles will be equal to 90° as shown;
(3x+5)° + 37° = 90°
open the parenthesis
3x+5 + 37° = 90°
3x+42 = 90
subtract 42 from both sides of the equation
3x+42-42 = 90-42
3x = 48
Divide both sides of the resulting equation by 3;
3x/3 = 48/3
<em>x = 16</em>
<em>Hence the value of x is 16°</em>
The simplified expression is
Step-by-step explanation:
Here, the total number of cards in a given deck = 52
let E : Event of drawing a first card which is King
Total number of kings in the given deck = 4
So, =
Now, as the picked card is NOT REPLACED,
So, now the total number of cards = 52 - 1 = 51
Total number of queen in the deck is same as before = 13
let K : Event of drawing a second card which is queen
So, =
Now, the combined probability of picking first card as king and second as queen = P(E) x P(K) =
Hence, the simplified expression is
