Answer:
D. x = sqrt(52).
Step-by-step explanation:
Since the line measuring 6 units bisects the top angle, there are two right angles. We can use the Pythagorean Theorem to solve for x.
a^2 + b^2 = x^2
4^2 + 6^2 = x^2
16 + 36 = x^2
52 = x^2
x = sqrt(52)
x = sqrt(2 * 2 * 13)
x = 2sqrt(13)
x = 7.211102551.
Hope this helps!
Step-by-step explanation:
1×100000+2×10000+9×1000+9×100+8×10+2×1
=100000+20000+9000+900+80+2
2 kilometers is equal to 2000 meters so she rode 2600 meter in total
