Help pleassssssssssssseeee
DiKsa [7]

Answer:

27in, 36in, 45in

Step-by-step explanation:

a = 27 \\ b = 36 \\ c = 45

{c}^{2} =  {a}^{2}  +  {b}^{2}

c = \sqrt{ {a}^{2} +  {b}^{2}  }

45{ = }^{?}   \sqrt{ {27}^{2} +  {36}^{2}  }

45  { = }^{?}   \sqrt{729 + 1296}

45  { = }^{?}   \sqrt{2025}

45 = 45

A polyhedron has the following characteristics. Find the missing value.
Eduardwww [97]
<span>Formula : V + F – E = 2
where V = number if vertices, F = number of faces and E = number of edges

<u>Question a:</u>

V + F - E = 2
V = 2 - F + E
V = 2 - 12 + 18 
V = 8

(a) </span><span>12 faces, 18 edges, <u>8</u> vertices

<u>Question b:</u>

</span>V + F - E = 2
<span>E = V+ F - 2
E = 14 + 8 - 2
E = 20

(b) </span><span>8 faces, <u>20</u> edges, 14 vertices</span>

Identify the correct justification for each step, given that ∠2 and ∠3 are complementary, and m∠1=m∠3.
blondinia [14]

Answer:

Option A is correct because sum of m<2 and m<3 are complementary. So m<2+m<3 =90° .

Step-by-step explanation:

Given: <2 and <3 are complementary angles.

Definition of complementary angles says if two angles sum is equal to 90 degrees then they are called complementary angles.

Statement                                                       Reason

1.<2 and <3 are complementary                 1. Given

2. m<2+m<3 =90°                                         2. Definition of complementary <s

3. m<1= m<3                                                  3. Given

4. m<1+m<2= 90°                                          4.Substitution property of =

5. <1 and <2 are complementary               5. Definition of complementary <s.

Option A matches with the given. We can not use addition properties of equality for statement 2 so, other options are incorrect.

So, according to the given options A is correct.
