Supplementary = equal to 180 degrees.
We can set up an equation.
2x + x = 180
Combine like-terms:
3x = 180
Divide both sides by 3 to isolate the x.
x = 60.
So one angle is 60 degrees and since the other one is twice of x, it is 120 degrees. If you add 120 and 60 degrees, you should get 180 degrees.
Nevertheless, the measures of the angles are 60 and 120 degrees.
Answer:
(a) 110 mm Hg
(b) 70 mm Hg
(c) 3/4 second
(d) see the attachment
Step-by-step explanation:
(a) The sine function has a maximum value of +1, so the maximum value of p is ...
pmax = 20·(+1) +90 = 20+90 = 110 . . . . . mm Hg
__
(b) The sine function has a minimum value of -1, so the minimum value of p is ...
pmin = 20·(-1) +90 = -20+90 = 70 . . . . . mm Hg
__
(c) The period of the sine function is 2π, so the value of t that makes the argument be 2π will be the period.
8π/3·t = 2π
t = 2π·3/(8π) = 3/4 . . . . . . multiply by the inverse of the coefficient of t
The period of her heartbeat cycle is 3/4 seconds.

Answer:
x = 10, y = 13
Step-by-step explanation:
Because EYD is 70, then FEY is also 70. Both triangles are identical.
This means:
45 + 70 + 7x - 5 = 180
7x = 70
x = 10
EFY and EDY are identical and this means:
7x - 5 = 5y
7*10 - 5 = 5y
5y = 65
y = 13
