Find the value of x. Round the length to the nearest tenth.​
Colt1911 [192]

To find value of <em>x</em> we can use the sine angle function. From definition and basics of trigonometry we know that,

\sin(\theta)=\dfrac{\mathrm{opposite}}{\mathrm{hypotenuse}}

In this case our opposite is <em>x</em> and our hypotenuse is <em>15m</em><em> </em>and our angle \theta is <em>35°.</em>

Therefore,

\sin(35^{\circ})=\dfrac{x}{15}

If we solve for <em>x</em>,

x=15\sin(35^{\circ})\approx\boxed{8.6\mathrm{m}}

Hope this helps.

\frac{\sqrt{3}}{6} a^{3} và \frac{a^{3} }{6}

Step-by-step explanation:

Câu 1: V = 1/3.2a.\frac{\sqrt{3}}{4}a^{2} = \frac{\sqrt{3}}{6} a^{3}

câu 2: Theo đề bài ta có SA là chiều cao và tam giác đáy SBC vuông tại S (hình chóp S.ABC đổi thành chóp A.SBC)

=> V = 1/3 SA.(diện tích tam giác SBC) = 1/3a.\frac{a^{2} }{2} = \frac{a^{3} }{6}
