Answer:

m angle BOC 120

m angle AOB 205

Step-by-step explanation:

So you are given mangle AOC+mangle BOC=mangle AOB.

mangle means measure of angle.

Let's do some substituting into our equation.

85+2x+10=4x-15

Solve for x... First I'm going to combine the like terms on the left hand side:

95+2x=4x-15

Add 15 on both sides

110+2x=4x

Subtract 2x on both sides

110 =2x

Divide both sides by 2

110/2 =x

x =110/2

x =55

So Recall mangle BOC=2x+10 =2(55)+10=110+10=120

And you also have mangle AOB=4x-15=4(55)-15=220-15=205

1.Use Euler’s Formula to find the missing number. Edges: 40

PtichkaEL [24]

Answer:

Euler's Formula states that:

V -E +F = 2 meaning that the vertices minus the edges plus the faces of a convex polyhedron will always equal two.

So, for the initial question, we have 40 edges and 24 faces.

So, vertices = 2 + Edges -Faces

Vertices = 2 + 40 - 24

Vertices = 18

Circle B's attributes were used to be organized because both shapes have 2 sets of parallel lines that are across from each other. The middle was organized because both shapes have 2 sets of parallel lines and 4 right angles.
