Sin = opposite/hypotenuse
so sin (x) = 12/13
answer is 12/13
Answer:
x = 7.2
Step-by-step explanation:
Let x be a positive number such that the distance between x and -3.8 on a number line is exactly 2 times the distance between x and 1.7.
Now. the distance between - 3.8 and x will be (x + 3.8) and the distance between x and 1.7 will be (x - 1.7) {Since x is a positive number}
(Assuming x is greater than 1.7}
Given that, x + 3.8 = 2(x - 1.7)
⇒ x + 3.8 = 2x - 3.4
⇒ x = 7.2 (Answer)
Step-by-step explanation:
just add all the given angles and equate it with 540° and then find x
x/2 + x/2 + x - 25 + 100 + x - 15 = 540°
3x + 60 = 540°
3x = 540 - 60
x = 480/3
x = 160°
on checking, the given shape values of x-25 and x - 15 are both still obtuse angles thus the answer is correct.
