Answer:
x = 6
Step-by-step explanation:
Based on the triangle sum theorem, the sum of the interior angles of a triangle = 180°
Given the following, right angle (90°), 60°, and (7x - 12)° as interior angles of the triangle, therefore:
7x - 12 + 90 + 60 = 180
Add like terms
7x + 138 = 180
7x + 138 - 138 = 180 - 138 (subtraction property of equality)
7x = 42
7x/7 = 42/7 (division property of equality)
x = 6
Answer:
5
Step-by-step explanation:
Answer:
Hence, the surface area of cone is:
282.6 cm^2 which is approx 283 cm^2.
Step-by-step explanation:
We are given:
- The circular base of a cone has a radius of 5 centimeters.
i.e. r=5 cm.
- The height of the cone is 12 centimeters
i.e. h=12 cm.
- The slant height is 13 centimeters.
i.e. l=13 cm.
Now we know that the surface area(S.A.) of cone is given by:

Hence by putting the value of l,r and π in the formula we get:

Hence the surface area of cone is 282.6 cm^2 which is approx 283 cm^2.
The answer is
6(10x-1)(x-1)
Answer:
0.10 for 1/4 of a mile so 8 would be 32 times more. Which would be .1 x 32 or $3.20
