If X=20°, Y=135°, what will Z be
Veronika [31]

The value of Z would be 225°

<h3>What is the angle at a point?</h3>

The angle at a point are angles that add up to 360°

Thus, X + Y + Z = 360°

X = 20°

Y = 135°

Then, Z = 360° - X - Y

Z = 360° - 20° + 135°

Z = 360° - 155°

Z = 205°

Therefore, the value of Z is 205°

Help thanksSSSSSSSSSS
Setler79 [48]

Answer:

  • \boxed{\sf{x=24}}

Step-by-step explanation:

<u>GIVEN:
</u>

To find the missing number in the proportion, you have to isolate it the term of x from one side of the equation.

\sf{\dfrac{8}{7}=\dfrac{x}{21}  }

First, thing you do is switch sides.

\sf{\dfrac{x}{21}=\dfrac{8}{7}  }

Multiply by 21 from both sides.

\Longrightarrow: \sf{\dfrac{21x}{21}=\dfrac{8*21}{7} }

Solve.

Multiply the numbers from left to right.

Use the order of operations.

PEMDAS stands for:

  • Parentheses
  • Exponents
  • Multiply
  • Divide
  • Add
  • Subtract

\Longrightarrow: \sf{\dfrac{8*21}{7}=\dfrac{168}{7}=24 }

\Longrightarrow: \boxed{\sf{x=24}}

  • <u>Therefore, the final answer is x=24.</u>

I hope this helps. Let me know if you have any questions.
