Answer:
![X = \sqrt{39}](https://tex.z-dn.net/?f=X%20%3D%20%5Csqrt%7B39%7D)
Step-by-step explanation:
![1)\ X^2 + 5^2 = Y^2\ (Y\ is\ the\ hypotenuse\ of\ the\ smaller\ triangle)](https://tex.z-dn.net/?f=1%29%5C%20X%5E2%20%2B%205%5E2%20%3D%20Y%5E2%5C%20%28Y%5C%20is%5C%20the%5C%20hypotenuse%5C%20of%5C%20the%5C%20smaller%5C%20triangle%29)
![2)\ Y^2 + 6^2 = 10^2](https://tex.z-dn.net/?f=2%29%5C%20Y%5E2%20%2B%206%5E2%20%3D%2010%5E2)
![3)\ X^2 + 25 + 36 = 100](https://tex.z-dn.net/?f=3%29%5C%20X%5E2%20%2B%2025%20%2B%2036%20%3D%20100)
![4)\ X^2 = 39](https://tex.z-dn.net/?f=4%29%5C%20X%5E2%20%3D%2039)
![5)\ X = \sqrt{39}](https://tex.z-dn.net/?f=5%29%5C%20X%20%3D%20%5Csqrt%7B39%7D)
Answer:
It is 90º
Step-by-step explanation:
Looking at the picture, we realize that the angle direcly beside it, EGD, is 90º. Now, both angles form a straight line, which equals 180º. 180-90= 90º.
Use rounding to get -6(0.2), and then multiply.
Use compatible numbers, such as -6(0.5), and then multiply.
Use front-end estimation to get -6(0.2), and then multiply.
Estimate -6.1(0.22)
Answer:
Use rounding to get -6(0.2), and then multiply.
Use front-end estimation to get -6(0.2), and then multiply.
Round the factors to the nearest whole number, and then multiply.
Step-by-step explanation:
Actual answer:
-6.1(0.22) = -1.342
Estimate answer:
-6 (.2) = 1.2
3.5 divided by 2.54=1.38 cm rounded to the nearest tenths place :)
