Aparallelogram has sides measuring 23.8 m and 35.3 m. the height corresponding to the 23.8-m base is 9.9 m. find the height, to the nearest tenth of a meter, corresponding to the 35.3-m base.

The value of x i.e DE is

Step-by-step explanation:

Given a parallelogram has sides measuring 23.8 m and 35.3 m. The height corresponding to the 23.8-m base is 9.9 m. we have to find the height corresponding to the 35.3-m base which is DE

Area of parallelogram ABCD=

                                               =

                                               =

Area of parallelogram ABCD=

                                               =

                                               =

Above two is the area of same parallelogram

⇒

⇒  

Hence,The value of x i.e DE is

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
