X would equal 70°.
For every triangle, all interior angles add up to 180°. This means that we can add together 42 and 68 to get 110°. Because the sum of all interior angles in a triangle must be 180°, we subtract 110 from 180 to see how much more we need, which gets us 70°.
I hope this helps!

Answer:
There are 213.36 centimeters in 7 feet.
Step-by-step explanation:
It is given that:
1 inch = 2.54 cm
We have to find centimeters in 7 feet.
We will convert feet to inches.
1 feet = 12 inches
7 feet = 12*7 = 84 inches
Now,
1 inch = 2.54 cm
84 inches = 2.54 * 84
84 inches = 213.36 cm
Therefore,
There are 213.36 centimeters in 7 feet.
Answer:Correct. He transformed the triangle according to the rule (x, y) → (-y, x).
Answer:

Step-by-step explanation:
1.5 : 915 = 610
610 ÷ 2 = 305
305 ÷ 3 = 101.66
101.66 × 4 = 406.66 mph
Thus, the answer is 406.66 × t
