Answer:
Q6.=24cm
Q7.= 9m
Step-by-step explanation:
answer of question 6 =
finding one of the legs of triangle -
Let the hypotenuse be x -
Therefore, 8² + 6² = x² (By Pythagoras Theory)
64+ 36 = 100
√64 + √36= √100
Because, √100 = 10 cm.
therefore, 26²cm =10²cm+ x²cm
676cm = 100 cm+ X²
676-100 cm = x²
576cm = x²
√576 = x
24 cm = x
therefore , x = 24 cm.
NOW THE ANSWER OF QUESTION 7 IS =
the ladder is the hypotnuse of the triangle that is forming with the ladder and wall is perpendicular and distance between wall and feet of ladder is the base.
Therefore , 15²m = 12m²+x²
225m = 144+ x²
225-144 = x²
81 = x²
√81 = x
9 m = x.
The height of building at which ladder is touching it is is 9 metre .
