<1 = 123
60 + 63 = 123
180 - 123 = 57
180 n- 57 = 123
Triangle angle-sum theorem
Alternate exterior angles theorem (?)
Same side interior angles theorem
idk what the last one is about sorry
hope this helps
Answer: B 21
Step-by-step explanation: There are 14 boys divide that by two you get seven and then you times that by three which equals 21
The length of the shadow is 14.2 m
Right angle triangle:
Right angle triangle has one of its sides as 90 degrees.
The height of the building is the opposite side of the triangle.
The distance from the top of the building to the tip of the shadow is 35 m is the hypotenuse side.
The length of the shadow is the adjacent side of the triangle.
Therefore,
c² = a² + b²
b² = 35² - 32²
b² = 1225 - 1024
b² = 201
b = √201
b = 14.17
b = 14.2 m
Hence the length of the shadow is 14.2 m.

Answer:
One
Step-by-step explanation:
The solution to the system is (1, 5)
z/4 + 5 >= 5.5
-5 -5 subtract 5 from both sides
z/4 >= 0.5
x4 x4 times both sides by 4
z >= 2.0
