Answer:

Step-by-step explanation:
x =135(being opposite angles of a parallelogram)
X=20° is your answer
Step-by-step explanation:
X+3x+10°=90°
4x+10°=90°
4x=(90-10)°
X=80/4
X=20°
Answer:
D.
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals. That means that their product is -1.
In option D, since the slopes are 1 and -1, their product is -1, and the lines are perpendicular.
Answer: D.

Step by step explanation
Answer:
26.3 m
Step-by-step explanation:
The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 37 m. Find the height of the building.
We solve the above question using Pythagoras theorem
c² = a² + b²
Where
c = Longest part of the triangle = 37 m
a = Height of the triangle = ?
b = Length of the shadow = 26 m
Hence:
37² = a² + 26²
a² = 37² - 26²
a = √37² - 26²
a = √(693)
a = 26.324893162m
Approximately = 26.3 m
