Question

Using tables, find the value of (2 sin A -cosA ) as a
decimal
(1) when A = 35°
(ii) when tan A = 0.2679​

Answer 1

Answer:

i)0.3280

ii)-0.4483

Step-by-step explanation:

i ) when a=35

(2sin A -cosA)=(1.1472- 0.8192)

=0.3280

ii) when tan A=0.2679

from this A= 0.2618

so (2sin A-cos A)= (0.5176-0.9659)

= -0.4483
