TFA-4.1b Nilai Fungsi

Diketahui f(x) = 5 - $$\sqrt[]{3}$$ tan 2(x+50⁰) nilai dari f(55) = . . .

Match the following

Perhatikan gambar disamping. Pasangkan nilai-nilai perbandingan trigonometri berikut!

r² = 6² + ​ 8²

r² = ​ (a)   + ​ (b)  

r² = ​ (c)  

r = $$\sqrt[]{100}$$

r = ​ (d)  

​ (a)   ² = x² + 12²

​ (b)   = x² + 144

x² = 169 - ​ (c)  

x² = ​ (d)  

x = $$\sqrt[]{25}$$

x = ​ (e)  

2 $$\sqrt[]{3}$$ +7 $$\sqrt[]{3}$$ = . . .

$$\left(5\sqrt[]{3}\right)^2\ =\ .\ .\ .\ .$$

$$\frac{3}{5}+\frac{5}{6}=.\ .\ .$$
