First find the length of the hypotenuse using pythagorean theorem
<span>c^2 = 5^2 + 7^2
c^2 = 25 + 49
c^2 = 64
c=8 (take the square root in both sides)
Since sin = opposite/hypotenuse,
sin = 5/8 = 0.625</span>
Answer: B C E F
Step-by-step explanation:
A is wrong as it should be the other way around
B is right
C is right
D is wrong as Natural numbers is a subset of rational numbers
E is correct
F is correct
x + (x + 3) +
= 75
so you will add up all of the x 's but NOT the x^2
2x + 3 +
= 75
Rearrange to put the x^2 in front of 2x
+ 2x + 3 = 75
subtract the 75 from both sides
+ 2x - 72 = 0
Okay. You can decompose 749 with these ways:
700 + 40 + 9
or
500 + 200 + 40 + 9
