Answer:

41.8°

Step-by-step explanation:

We solve using the Trigonometric function of Sine

Hypotenuse = 15cm

x = θ

Opposite = 10cm

sin θ = Opposite/Hypotenuse

sin θ = 10/15

θ = arc sin ( 10/15)

θ = 41.810314896°

θ = Approximately to 1 decimal place = 41.8°

Therefore, x = θ = 41.8°

Express x in terms of a and b:<br> b−7x=a−b

quester [9]

Answer:

Step-by-step explanation:

b - 7x = a - b....subtract b from both sides

-7x = a - b - b....combine like terms

-7x = a - 2b....divide both sides by -7

x = (a - 2b) / -7....or it could be written as x = -1/7a + 2/7b
