Answer:
∠KXN and ∠QXT
Step-by-step explanation:
The measure of each angle is the difference of the scale values that the rays intercept. (The same scale needs to be used for each ray.) Of course, complementary angles have a sum of 90°.
Here, we'll refer to angle aXb as "ab".
NP = 95 -35 = 60
PQ = 35 -20 = 15 . . . not complementary to NP
__
KN = 165 -95 = 70
QT = 20 -0 = 20 . . . complementary to KN ⇒ your answer
__
JK = 180 -165 = 15
PQ = 35 -20 = 15 . . . not complementary to JK
__
JK = 15
NK = KN = 70 . . . not complementary to JK
Differentiating both sides of
with respect to 
yields
At the point (3, 4) (so 
and 
), the tangent line has slope
Then the tangent line to (3, 4) has equation
Hey there!
"9 pounds more than" means that you'll be adding 9 to the expression.
"half the weight w" means that you'll be calculating half of w each time you solve the equation, or 0.5w.
Your entire expression will be 0.5w + 9.
Hope this helped you out! :-)
So we have lengths a and b and are given:
2a+2b = 66 => a+b = 33 => a= 33-b
a*b = 272
plug in one into the other:
(33-b)b = 272 => -b^2 +33b - 272 = 0
Can be factored as (b-16)(b-17) = 0, if you don't "see" this immediately, use the well known abc formula to find b.
So a=16 and b=17 or vice versa.
