Answer:
9
Step-by-step explanation:
22x = 198
divide both sides by 22
22x/22 = 198/22
x = 9
Answer:
109 degrees
Step-by-step explanation:
Since we can see that the line on the top, the one across the yellow box, is the main one, and that one measures 180*, so that means that we have to just subtract 180 by 71, and that will be our answer!
180-71 =109
So, the angle of the missing angle is 109 degrees.
Another proof that this is your answer is that 109 degrees is obtuse, and we can easily say that the angle here is also obtuse.
The difference of two squares. The number which, when multiplied together three times yields the original number.
Answer:
114 units²
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, so
AB = CD , that is
13x - 7 = 5x + 9 ( subtract 5x from both sides )
8x - 7 = 9 ( add 7 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
Then
5x + 9 = 5(2) + 9 = 10 + 9 = 19
3x = 3(2) = 6
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height ), thus
A = 19 × 6 = 114 units²
