Step-by-step explanation:

the law of sines :

a/sin(A) = b/sin(B) = c/sin(C)

with the sides being opposite to the angles.

so,

14/sin(80) = x/sin(60)

x = 14×sin(60)/sin(80) ≈ 12.3cm

1b. b. At midnight the temperature is -7°C. At midday the temperature is 4°C. By how much did the temperature rise? * 1 point Yo

ElenaW [278]

Answer:

$Rise = 11^\circ C$

Step-by-step explanation:

Given

$Midnight \to -7^\circ C$

$Midday \to 4^\circ C$

Required

The temperature rise

This is the difference between the final and the initial temperature

$Rise = Midday - Midnight$

$Rise = 4^\circ C - -7^\circ C$

$Rise = 4^\circ C +7^\circ C$

$Rise = 11^\circ C$
