1. draw the parallelogram with side 20cm and 25cm respectively and also the diagonal as well.
2.Clearly it forms a triangle in the parallelogram with three known lengths of side.
3.Using the cosine rule : c^2=b^2+c^2 -2bc cos c to find the obtuse angle.
Answer:
Step-by-step explanation:
can be represented as 
and ![\sqrt[3]5}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D5%7D)
can be represented as 
. Therefore, the expression can be rewritten as:
The rule for multiplying two exponents with the same base is you add the exponents. For example: 
We can use the same property to get:
which is just after you add the fractions
Answer:
36
Step-by-step explanation:
56=7-3[4+{8-4(4+5-3)}]
56=7-3[4+{4(4+5-3)}]
56=7-3[4+{16+20-12)}]
56=7-3[4+24]
56=4[28]
56=92
56-56=92-56
