Hola! UwU
Primero, pones los valores UvU
Sen37° = 3/5
Sen30° = 1/2
Sen45° = √2/2
Tg45° = 1
Tg60° = √3
Tg37° = 3/4
Tg74° = 24/7
Ctg53° = 3/4
Sec45° = √2
Csc30° = 2
Ahora, resuelves UvU
01.
E = (Sen37° + Tg45°) / Csc30°
E = (3/5 + 1) / 2
E = (3/5 + 5/5) / 2
E = (8/5) / 2
E = (8×1)/(5×2) ===> E = 8/10 ===> E = 4/5 ===> d) 0,8
02.
E = (Sec45° + Tg60°) / 2 × (Sen30°)
E = (√2 + √3) / 2 × (1/2)
E = (√2 + √3) / 2/2 ===> E = (√2 + √3) / 1 ===> aprox. a) π
03.
4x × Sen30° = Sec(^2)45° + Csc30°
4x × 1/2 = (√2)^2 + 2
4x/2 = 2 + 2
2x = 4 ===> x = 4/2 ===> b) x = 2
04.
M = (tg37° + Ctg53°) / (Sen(^2)45°)
M = (3/4 + 3/4) / (√2/2)^2
M = (6/4) / ((√2^2) / (2^2))
M = (3/2) / (2/4)
M = (3/2) / (1/2) ==> M = (3×2) / (2×1) ==> M = 6/2 ==> c) 3
05.
A = 7tg74° + 5Sen37°
A = 7 × (24/7) + 5 × (3/5)
A = (7 × 24)/7 + (5×3)/5 ===> A = 24 + 3 ===> a) 27
Besitos y abrazos UvU
P.D. Dame coronita si quieres UwU
