Question

Calcule as razões trigonométricas:

Answer 1

figura 1

b = 24
c = 10
a = 26
bc = ah
24 * 10 = 26h
26h = 240
h = 240/26 = 120/13 = 9.23
m + n = a
m + n = 26
m = 26 - n ****
b² = a * m
24² = 26n
26m = 576
n = 576/26 = 22,15 *****

m = 26 - 22,15
m = 3,85 ***

figura 2
a = 10
b = 8
a² = b² + c²
10² = 8² + c²
100 - 64= c²
c² = 36
c = V36 = 6 ****
bc = ah
8 * 6 = 10h
10h = 48
h = 48/10 = 4,8 ****
b² = am
8² = 10m
10m = 64
m = 64/10 = 6,4 *****
m + n = a
6,4 + n = 10
n = 10 - 6,4 = 3,6 ****
