Answer:
Step-by-step explanation:
take x as reference angle
using tan rule
tan x=opposite/adjacent
tan x=9/5
tan x=1.8
x=tan 61 degree
x=61 degree
for remaining angle
remaining angle+90+61=180 degree(being sum of interior angle of a triangle)
remaining angle=180-151
remaining angle=29 degree
Recall the Ratio for tan
Tan(theta) = opposite / adjacent
Tan (x) = 9 / 5
solve for x (use Tan^-1(...) )
88:132:44
Divide 264 by 6 (2+3+1) = 44
2*44=88
3*44=132
1*44=44
x = 2.667
so first you wanna isolate the x by adding 2 to both sides
3x - 2 = 6 ---> 3x = 8
then divide both sides by 3 to get the x alone
x = 8/3 = 2.667
