Answer:

60.2

Step-by-step explanation:

86 / 90 = x / 63

cross - multiply

90x = 86 (63)

90x = 5418

x = 60.2

Answer: x = 75.7 cm

Step-by-step explanation:

In the given picture, we are given a right triangle.

The length of hypotenuse = 85 cm

Angle opposite to x= [tex]63^{\circ}[/tex]

Using trigonometry,

[tex]\sin\theta=\dfrac{\text{Side opposite to }\theta}{\text{Hypotenuse}}\\\\\Rightarrow\ \sin63^{\circ}=\dfrac{x}{85}\\\\\Rightarrow\ x=85\times\sin63^{\circ}\\\\\Rightarrow\ x=85\times0.89100652418\\\\\Rightarrow\ x=75.7355545553\approx75.7\ cm[/tex]

Hence, the value of x = 75.7 cm
