Answer:
B=45 Degrees
Step-by-step explanation:
You can use law of sines to answer. Law of Sines states that
. That means that
. Multiplying 8 to both sides gives us
. By using inverse of sin, we get
. Plugging that into a calculator gives us b=45 degrees.

Answer:
x = 3
y = 15
Step-by-step explanation:
If △XPS ≅△DNF, their corresponding sides would be congruent. This implies that:
XP ≅ DN
PS ≅ NF
XS ≅ DF
Given that:
XP = 4y - 3
DN = 57
NF = 51
XS = 17x + 3
DF = 54
Therefore:
XP = DN
4y - 3 = 57 (Substitution)
Add 3 to both sides
4y = 57 + 3
4y = 60
Divide both sides by 4
y = 60/4
y = 15
Also,
XS = DF
17x + 3 = 54 (substitution)
Subtract 3 from each side
17x = 54 - 3
17x = 51
Divide both sides by 17
x = 51/17
x = 3
No. 26,341 is not evenly divisible by 3 .
Here's the trick you can use to decide this
just by looking at a big number:
==> If a number is divisible by 3, then the
sum of its digits is divisible by 3.
I've never taken the trouble to figure out why this works,
but it does work. I didn't make it up. It's widely known.
So let's look at 26,341 .
The sum of the digits is (2 + 6 + 3 + 4 + 1) = 16 .
16 is not divisible by 3 , so 26,341 is not divisible by 3 .
Is that cool or what !
