Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

Let's first establish that the shape is a triangle meaning that the following formula is applicable as displayed below:

Angle sum of a triangle = 180°

As well as this, the shape is an equilateral triangle meaning that each angle of the triangle is equivalent in value. Also, the following formula is also applicable as displayed below:

Each angle of an equilateral triangle = the same value

Therefore:

Each angle of an equilateral triangle = angle sum of a triangle ÷ no. of angles in a triangle = 180° ÷ 3 = 60°

Based on this, the following is applicable:

2x - 4 = 60°

2x = 60 + 4

2x = 64

x = 64 / 2

x = 32°

ANSWER:

Therefore, the answer is:

The value of ( x ) is 32°

Can someone help me? ​
Rasek [7]

Step-by-step explanation:

given \:  - 5n = 4m

making m the subject first by dividing through by 4

\frac{ - 5}{n}  =  \frac{4m}{4}

m =  \frac{ - 5n}{4}

from the question, given n = -1 ,0 ,1

so when n= -1

m =  \frac{ - 5( - 1)}{4}

m =  \frac{5}{4}

when n=0

m =  \frac{ - 5(0)}{4}

m =  \frac{0}{4}

m = 0

when n=1

m =  \frac{ - 5(1)}{4}

m =  \frac{ - 5}{4}

8x-5y=21 simultaneous linear equation<br>2x+9y=-5
olya-2409 [2.1K]

Answer:

x=2 and y=-1

Step-by-step explanation:

If two equations are given, we can solve one of the equation in terms of single variable and put it in the other equation which will further give the value of x and y.

For the given equations:

8x-5y=21              Equation:1

2x+9y=-5             Equation:2

Solving equation multiply equation 2 with 4 on both the sides

8x+36y=-20        Equation 3

Subtracting Equation:3 from Equation:1

8x-5y-(8x+36y)=21-(-20)\\8x-5y-8x-36y=21+20\\-41y=41\\y=-1

Putting value of 'y' in Equation:2 which will give the value of x

2x+9y=-5\\2x+9(-1)=-5\\2x-9=-5\\2x=4\\x=2

Please help I don’t understand math
andrew-mc [135]

Answer:

x = 12

Step-by-step explanation:

The sum of the two smaller angles is 140

80+5x = 140

Subtract 80 from each side

80+5x-80 =140-80

5x = 60

Divide each side by 5

5x/5 = 60/5

x = 12

(05.02) PLEASE ACTUALLY ANSWER AND EXPLAIN WELL!! :)
Nadusha1986 [10]

Answer:

  • x = 40°

Step-by-step explanation:

Straight angle is equal to 180°

Angle x, 60° and 80° form a straight angle.

<u>Then we have following equation to solve for x:</u>

  • x + 60° + 80° = 180°
  • x + 140° = 180°
  • x = 180° - 140°
  • x = 40°
