Answer:
Option B. 134.58 cm²
Step-by-step explanation:
Since one of a triangle with two sides and angle opposite to the third side is represented by area = (a.c sinθ)
Since a = 14 cm
c = 20 cm
and θ = 74°
By putting thee values in the formula
Area = (20) (14) (sin74°)
= 140(0.9613)
= 134.58 cm²
Therefore, option B is the answer.

Answer:
Use the appropriate entry method for piecewise functions for the graphing calculator of interest.
Step-by-step explanation:
For Desmos, the entry looks like ...
f(x) = {x ≤ 2: -2x-1,-x+4}
_____
For a TI-84 calculator, the entry may look like ...
Y₁ = (-2X–1)(X≤2) + (-X+4)(X>2)
The symbols ≤ and > come from the TEST menu, which is the (2nd) shift of the MATH key.
Note that the function is the sum of the pieces, each piece multiplied by a test. For something like 0≤x<2, the multiplier would be a pair of tests:
... (0≤X)(X<2)
