Multiply through by 7:-
3x - 14 = 105
3x = 119
x =119/3 = 39 2/3
Answer:
11/4
Step-by-step explanation:
tan(90-x)=cot(x) by cofunction identity
tan(90-x) is therefore the reciprocal value of tan(x) since tan(x) is the reciprocal of cot(x) or vice versa.
tan(90-x)=11/4 since tan(x)=4/11
Answer:
Blank area:40cm²
Shadow area:100cm²
Step-by-step explanation:
