Question

Which equation would help find the measure of ZM?

O x +52 + 78 = 180
O 52 + x = 180 + 78
O 180 + 52 = 78 + x
O 180 + x = 78 + 52

Answer 1

The answer is x + 52 + 78 = 180

Step-by-step explanation:

The sum of all 3 angles in a triangle is 180.

x + 78 + 52 = 180

x = 180 - 78 - 52

x = 50

Answer 2

`\huge \boxed{ \boxed{ \sf x + 52 ^(o) + 7 {2}^(o) =18 {0}^(o) }}`

Step-by-step explanation:

to understand this

you need to know about:

• triangle
• equation
• PEMDAS

given:

• 
  `\angle V=52°`
• 
  `\angle P=78°`

to find:

• the equation

tips and formulas:

• a triangle contains 180°

let's solve:

`\text{since a triangle contains 180° the sum of the interior angles has to be 180°}`

`\text{therefore the equation is}`

`\mathfrak{x + {52}^(o) + {78}^(o) = 180 ^(0) }`
