Angle 4 should have the same measure as the angle already shown. This is because of the vertical angles theorem.
To figure out the two remaining angles we can use math.
We start by knowing that the measure of all of the angles combined should equal 360 degrees. So we would subtract the measures of angles 1 and 4.
360-(106*2)=148
Then we divide 148 by two because there are two angles that are equal in measure.
148/2=74
a. Angle 2= 74 degrees
b. Angle 3= 74 degrees
c. Angle 4= 106 degrees
Answer:
Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.
An ionic bond is held together by the electrostatic attraction between ions that are near one another. Electrostatic attraction is the attraction between atoms that have opposite charge and holds the atoms together in ionic bonds.
Answer:
55
Step-by-step explanation:
The three angles form a straight line, so they add to 180.
x + x + 70 = 180
Combine like terms
2x+70 =180
Subtract 70 from each side
2x+70-70 =180-70
2x= 110
Divide by 2
x = 55
SQT = x
So SQT = 55
27.5/100=11/x
11 x 100 = 27.5x
1100=27.5x
1100/27.5=x

Answer:
f(x)=x^2+3
f(x+y)=(x+y)^2+3
this is done by replacing x with (x+y)
f(x+y)=x^2+2xy+y^2+3
therefore : f(x+y)= x^2+y^2+2xy+3
