Answer:
35.6 °C
Step-by-step explanation:
Let the °C be X
The upper scale reading for a Fahrenheit thermometer is 212 °F while the lower scale reading is 32 °F. On the Celsius thermometer, the corresponding scale readings are 100°C and 0°C respectively.
There a reading of 96°F would be
=
=
cross multiply
Divide both sides by 180
=
x = 35.5555
x ≈ 35.6

Step-by-step explanation:
Using the sum/ difference → product formula
cos x - cos y = - 2sin( )sin (
)
sin x - sin y = 2cos ( )sin (
)
Given
(cosA - cosB)² + (sinA - sinB )²
= [ - 2sin()sin(
) ]² + [ 2cos(
)sin(
) ]²
= 4sin² ( )sin² (
) + 4cos² (
)sin² (
)
= 4sin² ( )[ sin² (
) + cos² (
) ← sin²x + cos²x = 1
= 4sin² ( ) × 1
= 4sin² ( ) = right side ⇒ proven
