Sagot:

# x = 8sqrt3 #

Paliwanag:

#Sec 30 ° = x / 12 #

# 1 / (cos30 ^ @) = x / 12 #

gamit ang "yunit ng bilog" maaari naming matukoy ang eksaktong halaga ng # cos30 ^ @ = sqrt3 / 2 #

# 1 / (sqrt3 / 2) = x / 12 #

# 2 / (sqrt3) = x / 12 #

cross multiply:

# 2 * 12 = xsqrt3 #

# 24 = xsqrt3 #

# x = 24 / sqrt3 #

isakatwiran ang denamineytor:

# x = (24sqrt3) / 3 #

# x = 8sqrt3 #

Sagot:

SA IBABA

Paliwanag:

# sec30 = x / 12 #

alam natin iyan # cos 30 = sqrt3 / 2 #

din #sec = 1 / cos #

samakatuwid #sec 30 = 2 / sqrt3 #

ATQ, # 2 / sqrt3 = x / 12 #

# 24 = sqrt3x #

# x = 8sqrt3 #

HOPE U GET IT !!
