Step-by-step explanation:
a is the answer to this question
Answer:
d=90 e=27 f=153
Step-by-step explanation:
The angle adjacent to d is 90 degrees. They both add up to 90. 180-90=190. D=90.
E is a vertical angle, congruent to 27.
E=27.
F is a linear pair with 27, which means it's supplementary (adds to 180). 180-27=153.
F=153.

Find the missing lengths of the sides.
Answers
Answer: x = 8, y = 8
Step-by-step explanation: If 8 is already on the exterior of the triangle then this means that every angle should also be 8. But, if this were an equilateral triangle, a triangle with equal sides, then ALL sides would HAVE to be 8. But since I don't have this information (if it's equilateral or not), then I can't be positive about this. Really hope this helps you!

What are the domain and range of the function represented by the table?
Answers
Answer:
Doman is always the x-intercept.
And Range is always the y-intercept.
Domain = {-5, 0, 5, 10, 15}
Range = {-1, 0, 1, 2, 3}
So the answer is C.
Can someone please help for this question?
Answers
x = y + 2
3x + 4y = 8x - 20
From the first equation y = x - 2. Substitute for y in the second equation.
3x + 4(x - 2) = 8x - 20
3x + 4x - 8 = 8x - 20
7x = 8x - 12
So x = 12
You should always check your answers for simultaneous equations
y = 10 because x = y + 2
3 x 12 + 4 x 10 = 8 x 12 - 20?
36 + 40 = 96 - 20. This is true!

Answers
Answer:
The domain is {3,6,−1,5,−4}
Step-by-step explanation:
Answer:
3,6,-1,5,-4.
Step-by-step explanation:
The domain is the x-value or the first number in the ordered pair. For example: (5,2). The x-value is 5 so that means that the domain is 5. Therefore, for this function, the domain will be 3,6,-1,5,-4.

Decking costs $1.75 per square foot. How much will it cost to build the deck?
Answers
Answer:
27
36 ft
45 ft
$189
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
original dimension = (8 x 9) / 2 = 36
(10 x 9) / 2 = 45
(6 x 9) / 2 = 27
cost of deck = sum of sides x cost per square feet
sum of sides = 36 + 27 + 45 = 108
108 x 1.75 = 189
