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= 63^{\circ}

Using trigonometry,

\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

Hence, the value of x = 75.7 cm

soldi70 [24.7K]

Answer:

- 75 - 32y

Step-by-step explanation:

2y-3[3-4(y-5)+2(1-3y)]

= 2y - 3(3 - 4y + 20 + 2 - 6y)

= 2y - 3(25 - 10y)

= 2y - 75 - 30y

= - 75 - 32y
