Answer:
10°
Step-by-step explanation:
x + 25 = 3x + 5. [Vertically Opposite Angles]
=> 25 - 5 = 3x - x
=> 20 = 2x

=> 10 = x
=> <u>x = 10</u><u>°</u><u>(</u><u>Ans)</u>
You need to solve the following equation:
-0.5x^2 +36x -161 = 451
Set right side to 0
-0.5x^2 +36x -612 = 0
Multiply by -2 to get rid of decimal and leading neg coefficient.
x^2 -72x + 1224 = 0
Use quadratic formula:
a = 1, b = -72, c = 1224

Therefore the min price to have 451 profit is $27.51
It’s the one you picked D
Answer:
Step-by-step explanation:
Corresponding parts of congruent triangle are congruent.
ΔSTU ≅ ΔKLM
a) TU = LM
b) KM = SU
c) LK = TS
d) ∠M = ∠U
e) ∠T = ∠L
f) ∠UST = MKL
g) ΔUST ≅ ΔMKL
h) ΔTUS ≅ ΔLMK
Would it be easier if you rounded 75 to 80?
