Answer:
Y1 is parallel to Y2 and L1 to L2.
Step-by-step explanation:
A line is 180°. To find the degree the angles I subtracted 117 and 63 by 180 to find thair respective angles. (Also 117+63 equil 180) meaning that the Y's and L's are parallel to each other.
Answer:0.2
area of sector =x°/360×π×r²
1unit²=x°/360×π×45²
360=x°×π×2025
i think this is your answer.
I believe the answer is B
Answer:18
Sin72=cosy
0.9511=cosy
Y=cos(inverse)0.9511
Y=18
