Sagot :

#1

x=60(Opposite angle)

[tex]\\ \tt\Rrightarrow x+y=180[/tex]

[tex]\\ \tt\Rrightarrow 60+y=180[/tex]

[tex]\\ \tt\Rrightarrow y=180-60=120[/tex]

#2

  • Radius=r=7cm

[tex]\\ \tt\Rrightarrow Perimeter=2\pi r[/tex]

[tex]\\ \tt\Rrightarrow Perimeter=2\times \dfrac{22}{7}(7)[/tex]

[tex]\\ \tt\Rrightarrow Perimeter=44cm[/tex]

And

[tex]\\ \tt\Rrightarrow Area=\pi r^2[/tex]

[tex]\\ \tt\Rrightarrow Area=\dfrac{22}{7}(7)^2[/tex]

[tex]\\ \tt\Rrightarrow Area=154cm^2[/tex]

#3

[tex]\\ \tt\Rrightarrow \dfrac{4}{3}=\dfrac{x}{15}[/tex]

[tex]\\ \tt\Rrightarrow 3x=60[/tex]

[tex]\\ \tt\Rrightarrow x=\dfrac{60}{3}[/tex]

[tex]\\ \tt\Rrightarrow x=20[/tex]

#4

[tex]\\ \tt\Rrightarrow (a+5)(3a-6)[/tex]

[tex]\\ \tt\Rrightarrow a(3a-6)+5(3a-6)[/tex]

[tex]\\ \tt\Rrightarrow 3a^2-6a+15a-30[/tex]

[tex]\\ \tt\Rrightarrow 3a^2+9a-30[/tex]

[tex]\\ \tt\Rrightarrow a^2+3a-10[/tex]

#5

[tex]\\ \tt\Rrightarrow Area=64[/tex]

[tex]\\ \tt\Rrightarrow side^2=64[/tex]

[tex]\\ \tt\Rrightarrow side=\sqrt{64}[/tex]

[tex]\\ \tt\Rrightarrow side=8cm[/tex]

I hope it helped U ❣️❣️❤️❤️
