What are the values of x and y in the equation
vaieri [72.5K]

Answer:

The correct choice is D

Step-by-step explanation:

Value of X=20 and then to know the value of y we need to add

52+52= 104

360-104= 256

256÷2= 128

Y=128

15 points please help!! :)<br> Find the value of x.
andriy [413]

Answer:

Question 4: -11

Question 5: -7

Step-by-step explanation:

Four

Every triangle has 180 degrees.

So all three angles add to 180

<em><u>Equation</u></em>

60 + 80 + x + 51 = 180

<em><u>Solution</u></em>

Combine the like terms on the left. This is the first time I've seen x be a negative value. Almost all of the time it isn't, which should make you wonder.

191 + x = 180    

Subtract 191 from both sides.

191 - 191 + x = 180 - 191

x = - 11

Five

If a triangle is a right triangle and one of the angles is 45, then so is the other one.

<em><u>Proof</u></em>

a + 45 + 90 = 180         Combine like terms on the left

a + 135 = 180                Subtract 135 on both sides.

a + 135-135=180-135    Combine the like terms

a = 45

<em><u>Statement</u></em>

That means 52 + x = 45 and here is another negative answer. Subtract 52 from both sides

52 - 52 + x = 45 - 52    Combine like terms.

x  = - 7

What is the value of y?<br> Y<br> Y<br> 60<br> O A. 120°<br> B. 60°<br> C. 40°<br> O D. 30°
Grace [21]

Answer:

B. 60°

Step-by-step explanation:

1. The measure of all angles in a triangle sum up to 180°. This means that y + y + 60 = 120.

2. (Solving)

Step 1: Simplify both sides of the equation.

  • (y+y)+(60)=180
  • 2y + 60 = 180

Step 2: Subtract 60 from both sides.

  • 2y + 60 - 60 = 180 - 60
  • 2y = 120

Step 3: Divide both sides by 2.

  • \frac{2y}{2}=\frac{120}{2}
  • y = 60

Step 4: Check if solution is correct.

  • (60)+(60)+60 = 180
  • 120 + 60 = 180
  • 180 = 180

Therefore, the answer is B. 60°.
