The map shows the intersection of three roads. Malcom Way intersects Sydney Street at an angle of 162°. Park Road intersects Syd

Y_Kistochka [10]

Answer:

The angle at which malcom Way intersects Park Road = 111 °

Step-by-step explanation:

Malcom Way intersects Sydney Street at $\theta_{1}$ = 162 °

Park Road intersects Sydney Street at $\theta_{2}$ = 87 °

The angle at which Malcom Way intersects Park Road $\theta_{3}$ = ?

We know that

$\theta_{1} + \theta_{2} + \theta_{3} = 360$

$\theta_{3} = 360 - \theta_{1} - \theta_{2}$

$\theta_{3} = 360 - 162 - 87$

$\theta_{3} = 111$ °

Therefore the angle at which malcom Way intersects Park Road = 111 °

Answer:

$=2xy+6x^2-6x$

Step-by-step explanation:

$-2x\left(-y-3x+3\right)\\\mathrm{Distribute\:parentheses}\\=\left(-2x\right)\left(-y\right)+\left(-2x\right)\left(-3x\right)+\left(-2x\right)\cdot \:3\\\mathrm{Apply\:minus-plus\:rules}\\\left(-a\right)\left(-b\right)=ab,\:\:+\left(-a\right)=-a\\=2xy+2\cdot \:3xx-2\cdot \:3x\\\mathrm{Simplify}\:2xy+2\cdot \:3xx-2\cdot \:3x:\quad 2xy+6x^2-6x\\2xy+2\cdot \:3xx-2\cdot \:3x\\2\cdot \:3xx=6x^2\\2\cdot \:3x=6x\\=2xy+6x^2-6x$
