As is shown in the figure attached:
1. "A" and 76º are congruents, because they are Alternate Interior angles, so A=76º.
2. "D" and "x" are congruents,
because they are Alternate Interior angles, so x=38º.
3. "A", "B" and "C" form a the triangle ABC. Then, we remember sum of the interior angles of a triangle is 180º, so we have:
76º+38º+B=180º
B=180º-76º-38º
B=66º
4. By definition, an exterior angle of a triangle is equal to the sum of the opposite interior angles to it. So, we can calculate the exterior angle "y" of the triangle ABC, as follows:
The opposite angles are: 76º and 66ª. Then, we obtain:
y=76º+66º
y=142º
Therefore, the answer is: The value of y is 142º.

<span>х is the first number
(x + 1) is the second number
(x + 2) is the third number
(x + 3) is the fourth number
</span>
x + x+1 + x+2 + x+3 = 230
4x + 6 = 230
4x = 230 - 6
4x = 224
x = 224/4
x = 56 the first number
56 + 1 = 57 the second number
56 + 2 = 58 the third number
56 + 3 = 59 the fourth number
Answer: 56, 57, 58, 59.
Answer:
d = -8
Step-by-step explanation:
Isolate the variable, d. Note the equal sign, what you do to one side, you do to the other. Divide -4 from both sides of the equation:

d = -8 is your answer.
