There isn't enough information to answer this question, sorry.
Answer:
60°
Step-by-step explanation:
Let angle BAE = angle ACD = x
BCD = AEC = 60°
EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°
EAC = 60° - x
BAC = EAC + BAE = 60° - x + x = 60°
5(b - 0.18b).....use the distributive property
5b - 0.90b <== ur equivalent expression
The area of a triangle can be found by using the formula A = bh/2
To find the area of the shaded region (the green section), we can find the area of both triangles and subtract.
Large triangle:
A = 28*36/2
A = 1008/2
A = 504km²
Small triangle:
A = 15*19/2
A = 285/2
A = 142.5km²
Subtract both triangles:
504 - 142.5 = 361.5km²
Therefore, the area of the shaded region is <u>361.5</u>km²
Best of Luck!
sub 2 for any "x"
3(2)^2-2(2)+1
6^2-4+1 i dont know if you need to simplify even more but if you do
36-4+1 32+1 31
i hope this helps you!
