Answer:
∠RST = 40°
Explanation:
We are given that:
SQ bisects angle RST.
This means that:
∠QST = ∠QSR
2x = 3x - 10
10 = 3x - 2x
x = 10
Therefore:
∠QST = 2x = 2(10) = 20°
∠QSR = 3x - 10 = 3(10) - 10 = 30 - 10 = 20°
Note that both angles are equal.
Now, we can get ∠RST as follows:
∠RST = ∠QST + ∠QSR
∠RST = 20 + 20 = 40°
Hope this helps :)
Includes critical information you need to identify the chemical
, Includes warnings about the chemical
, Legible are the requirements for chemical labels
<u>Step-by-step explanation:</u>
Labels need to produce guidance on how to manage the chemical so that chemical users are notified about how to guard themselves. That data about chemical hazards be dispatched on labels using quick visual notations (Legible) to inform the user, granting instant identification of the hazards.
Labels, as described in the HCS, are a relevant group of written, printed or graphic information elements concerning a hazardous chemical that are attached to, printed on, or added to the immediate container of a hazardous chemical, or to the outside packaging.
In short, for a vertical parabola, namely one whose independent variable is on the x-axis, usually is x², if the leading term coefficient is negative, the parabola opens downward, and its peak or vertex is at a maximum, check the picture below at the left-hand-side.
and when the leading term coefficient is positive, the parabola opens upwards, with a minimum, check the picture below at the right-hand-side.
Example
from pir^2 ro pi(2r)^2
pi(2r)^2=pi4r^2=4pir^2
basicaly we look for any no options and ones where second is 4 times first
B
pi2^2, if it is double, pi4^2
B
