Answer:
d) 4 + 7 - 2
Step-by-step explanation:
7 + 2 - 4 = 5
2 + 7 - 4 = 5
7 - 4 + 2 = 5
4 + 7 - 2 = 9
sin(
)=Sin(
-0) =Sin 0=0
Option C Sin(
)=0
Also, using unit circle, Sin(
)=0
Answer:
m=9/8
Step-by-step explanation:
64m^2 -5=76
64m^2 =76+5
64m^2=81
m^2=81/64
m=
m=9/8
The answer is 1/4
because the answer 3/12 = 1/4
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for B
B = 180° - (90 + 47)° = 180° - 137° = 43°
-------------------------------------------------------------
tan47° =
= 
Multiply both sides by 14
14 × tan47° = a, thus
a ≈ 15.0 (to the nearest tenth )
---------------------------------------------------------------
cos47° =
= 
Multiply both sides by c
c × cos47° = 14 ( divide both sides by cos47° )
c =
≈ 20.5 ( to the nearest tenth )
