1; find the value of :
5 tan2 O + 2 sin2 0 - 3​

Answer 1

Answer:

pls mark as brainleist pls mark as brainleist pls mark as brainleist pls

Step-by-step explanation:

 know that the values of the trignometric functions: 

sin300=21, tan450=1, cos300=23, tan300=31 and cos450=21

 

Therefore, the value of 2sin300+cos300+tan4505sin2300+cos2450−4tan2300 is:

      

2sin300+cos300+tan4505sin2300+cos2450−4tan230
