X+Y=42
X-Y=4
Add both equations.
X+X+Y-Y=42+4
2X=46
X=23
23-Y=4
Y=23-4=19
23 and 19
Answer:
x=60° , y=30° , z= 75°
Step-by-step explanation:
note...an equilateral triangle has the same angles all equal to 60°. so based on this x is 60°
the angle next to y is on a straight line therefore
60 +y =90
y=90-60
y=30°
the triangle with the y and z angles is an isosceles triangle...so the base angles must be equal
z+z+30=180
2z+30=180
2z=180-30
2z=150
![\frac{2z}{2} = \frac{150}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2z%7D%7B2%7D%20%3D%20%20%5Cfrac%7B150%7D%7B2%7D%20%20)
z=75°
<span>If water and oil are combined in a container, the resulting liquid is a suspension. Water and oil do not mix. They form a heterogeneous mixture (a mixture whose composition is not uniform). The kind of heterogeous mixture that water and oil form is a suspension because the two lquids separate and can be easily distinguished. An emulsion, is an heterogenous mixture where small drops of one of the liquids disperse into the other liquid, so they form a stable mixture that will not separate quickly. Mayonaisse is an example of emulsion, because it consists of two liquids (oil an eggs) dispersed one into the other. Milk is also a emulsion of fat and water. So the specif term for the liquid resulting from water and liquid combined in a container is the option A. suspension.</span>
