<3 and <4 are supplementary angles. Given m<3 = 56°, find m<4.

liubo4ka [24]

m<3=56°
m<4=?

Both are supplementary angles.

$\\ \rm{:}\twoheadrightarrow m$

$\\ \rm{:}\twoheadrightarrow 56+x=180$

$\\ \rm{:}\twoheadrightarrow x=180-56$

$\\ \rm{:}\twoheadrightarrow x=124$

6. Which property is illustrated by the equation<br> ma + mb = m(a + b)?<br> what’s the answer

BigorU [14]

Step-by-step explanation:

It's the <em>DISTRIBUTIVE PROPERTY</em>:

m(a + b) = ma + mb

$m\cdot(a+b)=m\cdot a+m\cdot b=ma+mb$

Other properties:

Commutative Property:

<em>of addition: a + b = b + a</em>

<em>of multiplication: a · b = b · a</em>

Associative Property:

<em>of addition: (a + b) + c = a + (b + c)</em>

<em>of multiplication: (a · b) · c = a · (b · c)</em>
