Answer:
-23/7
Step-by-step explanation:
y2 - y1 / x2 - x1
48 - 2 / -7 - 7
46 / -14
= -23/7
Answer:
x = 42, y = 30
Step-by-step explanation:
From the given figure, we have to find the value of x and y.
The measurement of an angle on a straight angle is 180 degrees.
Using this concept, we have
Now, we know that the sum of consecutive interiors angles is 80 degrees. Hence, we have
Plugging the value of y in equation (1)
Hence, the values of x and y are
x = 42, y = 30
7.75 is the answerto the equation
Answer:
84 in²
Step-by-step explanation:
The side lengths of the triangle are 3 consecutive integers whose sum (the perimeter) is 42. The average of those integers, 42/3 = 14, is the middle of the three, so they are 13, 14, 15. We're told the perimeter is in inches, so all of these dimensions are inches.
These are the last three of 4 consecutive integers, so the first, the height of the triangle, is 12. The base of the triangle is the 3rd of the four integers, so is 14. Then the area is ...
A = (1/2)bh = (1/2)(14)(12) = 84 . . . . . square inches.
