Answer:
x = 71°
Step-by-step explanation:
The angles of any triangle will always amount to 180°.
Which means: (Angle of A) + (Angle of B) + (Angle of C) = 180°
Placing the known values into that equation will always let you know the third angle of any triangle.
(Angle of A) + (Angle of B) + (Angle of C) = 180°
(38°) + (71°) + (x) = 180°
109° + x = 180°
Solve for x by subtracting 109° from both sides
x = 180° - 109°
x = 71°
OR you can add the other two known angles 38° + 71° = 109°
This subtracted from the 180°
180° - 109° = 71°
Answer:
I'm going to calculate with sides 28 m
4,900 tiles used
Step-by-step explanation:
Area restaurant 28x28 = 784 m squared
each tile 40 cm = 0.4m
area of tile 0.4x0.4 =0.16
784/0.16 = 4,900
Answer: B
