Answer:
It's choice 2. c = 3 sin 45 / sin 40.
Step by-step explanation:
m< A = 180 - 45-95
= 180 - 140
= 40 degrees.
So by the Sine Rule:
c / sin 45 = 3 / sin A
Cross multiply:
c sin A = 3 sin 45
c = 3 sin 45 / sin 40.
Hi!
One deck of card has 52 cards, and in every deck there are 4 queens.
We will find the probability of pulling out the queen from the deck by diving the number of queens by the number of cards in the deck, like this:
4/52 = 1/13
Hope this helps!
Answer:
PR= 8
ST=5
Step-by-step explanation:
PQ and PR are congruent so
2x=8
x=4
2*4=8
PR=8
ST and TU are congruent so
5z=2z+3
3z=3
z=1
5*1=5
ST=5
The missing exponent is 21 :)
Explanation: when dividing exponents, subtract them so in this case, it’s 25-19 to get 6 as the answer
