Answer:
D
Step-by-step explanation:
Lateral SA = area of the 4 triangles
Formula to be used :-
Area (triangle) = 1/2bh
=> 4 x 1/2 x 9 x 12
=> 108 x 2
=> 216 cm²
Total SA = LSA + area of the square
Formula to be used :-
Area (square) = side length x side length
=> 216 + 9 x 9
=> 216 + 81
=> 297 cm²
<u>The correct option is (D).</u>
The equation solution is y=1, so the two ordered pairs may contain any value of x and a value of 1 for y. (Ex: (-8,1) and (8,1))
It would be 196/9 or 12.7777 in decimal
Answer:
x = 90
Step-by-step explanation:
The 90-degree angle and "x" form a straight line. The degree measurement of a straight line is 180. That means that if one adds 90 and "x", they will get 180, and therefore, x equals 90.
You just put the numbers in the formula 3x30 = 90 km
