If the angles of a triangle are (2y - 5)degrees, (y + 20)degrees, and (3y-5) degrees what are the values of the angles

NNADVOKAT [17]

Answer:

<h3> $\boxed{ \boxed{ \bold{ \sf{51.68 \: , \: 48.34 \:, \: 80.02}}}}$ </h3>

Step-by-step explanation:

Let's solve:

As we know that the sum of angles of traingle adds to 180°

$\sf{2y - 5 + y + 20 + 3y - 5 = 180}$

Collect like terms

⇒ $\sf{6y - 5 + 20 - 5 = 180}$

⇒ $\sf{6y + 15 - 5 = 180}$

⇒ $\sf{6y + 10 = 180}$

Move constant to right hand side and change it's sign

⇒ $\sf{6y = 180 - 10}$

Calculate the difference

⇒ $\sf{6y = 170}$

Divide both sides of the equation by 6

⇒ $\sf{ \frac{6y}{6} = \frac{170}{6} }$

Calculate

⇒ $\sf{y = 28.34}$

Now, let's replace the value:

⇒ $\sf{2y - 5 = 2 \times 28.34 - 5 = 51.68}$

⇒ $\sf{y + 20 = 28.34 + 20 = 48.34}$

⇒ $\sf{3y - 5 = 3 \times 28.34 - 5 = 80.02}$

Hope I helped!

Best regards!!

Answer: Since 3−5+2=0, then 2

is the additive inverse of 3−5 is 2

Since 5−3−2=0, then −2is the additive inverse of 5−3. is -2

Step-by-step explanation: additive inverse

The additive inverse of any number

is the number that gives zero when added to

. Example: the additive inverse of

5 is −5.
