X=1
solve for x by simplifying both sides
Answer:
2/5 or 2:5
Step-by-step explanation:
Face Card:
The face cards in a deck are the Jack, Queen, and King. There are 4 of each card (1 in each suit), for a total of 12 face cards.
Spade:
1/4 of all the cards in a deck are spades, so 52/4= 13 spades.
When added, the numerator of the probability is 25, however, because the Jack, Queen, and King of Spades are duplicated, we have to subtract 3.
25-3=22
22/55
when simplified: 2/5
Answer:
1. 135°
2. 114°
3. 118°
4. 81°
Step-by-step explanation:
Let "x" represent the measure of the indicated angle in each problem.
1. x = 135° (corresponding angles theorem)
2. x = 180° - 66° (same-side interior angles theorem)
x = 114°
3. x = 118° (alternate interior angles theorem)
4. x = 81° (alternate exterior angles theorem)
1,2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60.
