Answer:

25°

Step-by-step explanation:

you take the angles you already know and add them up. subtract that sum with 180° to get x.

Answer:

F = 7

Step-by-step explanation:

Euler's formula relating faces, edges, vertices is

V - E + F = 2

8 - 13 + F = 2

What is 2x + 30 = 186 First Answer will get Brainliest
vekshin1

2x+30=186

We move all terms to the left:

2x+30-(186)=0

We add all the numbers together, and all the variables

2x-156=0

We move all terms containing x to the left, all other terms to the right

2x=156

x=156/2

x=78

The hypotenuse of a right triangle is 10 meters and its
liberstina [14]
<h2><u>Solution</u> :</h2>

Let's solve by using Pythagoras theorem,

\hookrightarrow \: (10) {}^{2}  =  {(x})^{2}  + (x + 2) {}^{2}

\hookrightarrow \: 100 =  {x}^{2}  +  {x}^{2}  + 4x + 4

\hookrightarrow \: 100 - 4 = 2 {x}^{2}  + 4x

\hookrightarrow \: 96 = 2 {x}^{2}  + 4x

\hookrightarrow \: 2 {x}^{2}  + 4x - 96 = 0

\hookrightarrow \: 2( {x}^{2}  + 2x - 48) = 0

\hookrightarrow \:  {x}^{2}  + 2x - 48 = 0

\hookrightarrow \:  {x}^{2}  + 8x - 6x - 48 = 0

\hookrightarrow \: x(x + 8)  - 6(x + 8) = 0

\hookrightarrow \: (x + 8)(x - 6) = 0

now there are two cases

Case 1 : when (x + 8) = 0

\hookrightarrow \: x + 8 = 0

\hookrightarrow \: x =  - 8

but the value of x can't be negative, since side of a triangle isn't a negative value .

Case 2 : when (x - 6) = 0

\hookrightarrow \: x - 6 = 0

\hookrightarrow \: x = 6

therefore the measure of other two sides are :

\hookrightarrow \: x = 6 \: units

\hookrightarrow \: x + 2 = 6 + 2  = 8 \: units

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \mathrm{TeeNForeveR }
