I may give the answer, but not the proper calculation so aware.
So we all know a triangle have 180 degree.
We have 180 - (2a + 6) - a = 90
So abandon the 6 and 90 at this point, we'll have 2a and a
180 - 90 - 6 = 84
84 / 3 = 28.
So a = 28, 2a + 6 = 62
90 + 28 + 62 = 180, which makes the answer valid.

Step-by-step explanation:
3 plus 3 is not 13
Answer:
The answer is below
Step-by-step explanation:
The scale for the drawing is 1 inch = 40 feet.
The right angled triangle has legs of 3 inches and 4 inches. Using the scale, the length of the legs is:
3 inches = 3 inch * 40 feet / inch = 120 feet and 40 inches = 4 inch * 40 feet / inch = 160 feet.
The area of a right angled triangle is half the product of the two legs. Hence:
Area of right angled triangle = 1/2 * 120 feet * 160 feet = 9600 ft²
The rectangle with dimensions of 1.5 inches and 2.5 inches. Using the scale, the length of the sides is:
1.5 inches = 1.5 inch * 40 feet / inch = 60 feet and 2.5 inches = 2.5 inch * 40 feet / inch = 90 feet.
The area of a rectangle is the product of the two sides. Hence:
Area of rectangle = 60 feet * 90 feet = 5400 ft²
The domain contains only natural numbers
.
Exponential bases must be whole numbers.
Initial values must be whole numbers.
The correct answer is:
The domain contains only natural numbers .
Explanation:
The domain of a geometric sequence is the set of term numbers. This is the position of each term in the sequence: first, second, third, etc.
Since the domain is the set of positions, there are no decimal or fraction numbers in the domain. There would be no "2 and a half" term; it goes from the second to third.
This means that the values between the terms of the sequence have no value, and the graph will not be connected.
Answer: B.
(The domain contains only natural numbers.)
