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

Answer:

sine 23 = x/21

Multiply both sides by 21

21 x sine 23 = x

Now, use a calculator and find the answer of the 21 times the sine of 23:

x = -17.7706284876

What is the value of y?<br> Y<br> Y<br> 60<br> O A. 120°<br> B. 60°<br> C. 40°<br> O D. 30°

Grace [21]

Answer:

B. 60°

Step-by-step explanation:

1. The measure of all angles in a triangle sum up to 180°. This means that y + y + 60 = 120.

2. (Solving)

Step 1: Simplify both sides of the equation.

$(y+y)+(60)=180$
$2y + 60 = 180$

Step 2: Subtract 60 from both sides.

$2y + 60 - 60 = 180 - 60$
$2y = 120$

Step 3: Divide both sides by 2.

$\frac{2y}{2}=\frac{120}{2}$
$y = 60$

Step 4: Check if solution is correct.

$(60)+(60)+60 = 180$
$120 + 60 = 180$
$180 = 180$

Therefore, the answer is B. 60°.
