It’s 15 because of Pythagorean theorem. 25 squared minus 10 squared is 15 squared.
Answer:
Step-by-step explanation:
So ,to create a word phrase, you have to identify all of the operations going on here...
5+(17 - 8)
within the parentheses, you have subtraction. that's usually called the "difference" in word phrases. you also have a 5 outside the parentheses, leaving it to be multiplied inside, and multiplication is typically referred to as a "product"
with that info, you can construct a word phrase such as "the product of 5 and the difference between 17 and 8" or "the difference between 17 and 8 multiplied by 5"
Answer:
x = 27/4
Step-by-step explanation:
3x + 2y = 12 and 5x – 2y = 42
Add the two equations together to eliminate y
3x + 2y = 12
5x – 2y = 42
-----------------------
8x = 54
Divide each side by 8
8x /8 = 54/8
x = 27/4
Answer:
See below in bold.
Step-by-step explanation:
(1) cosec ( x + 10) = 3
Now cosec x = 1/sin x so
1 / sin (x + 10) = 3
3 sin (x + 10) = 1
sin (x + 10) = 1/3
x + 10 = 19.47 , 160.53 degrees
x = 9.47, 150.53 degrees.
(ii) cot (x - 30) =0.45
cot (x - 30)= 1 /tan (x- 30) so we have
tan (x - 30) = 1 / 0.45 = 2.2222
x - 30 = 65.77 degrees
x = 95.77 degrees.
