Answer: sqrt(19)/10
Step-by-step explanation:
sinx=0.9
x=arcsin(0.9)
Insert x for cos(x):
cos(arcsin(0.9)=
Use identify
, so

Sorry if this is confusing.
29 - 29 x 15= 24.65
24.65 + 24.65 x .07= 26.3755 which rounds to 26.38
The answer is $26.38
The value of x would be 8
The answer is: " 132° " .

Note: m∠9 = m∠11 = m ∠16 ;
So; m∠11 + m∠16 = 132 .
