Answer:
angle 5 = 102
Step-by-step explanation:
angle 2 = angle 6 { they are corresponding angles }
and then angle 6 and angle 5 = 180
78 + angle 5 = 180
angle 5 = 180-78
angle 5 = 102
The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.
Step-by-step explanation:
Let,
The longer leg = x
The shorter leg = x-7
Hypotenuse = x+7
Using Pythagoras theorem;

Either,
x= 0
Or,
x-28=0 =>x=28
As length cannot be zero, therefore,
Longer side = 28cm
Shorter side = x-7 = 28-7 = 21cm
Hypotenuse = x+7 = 28+7 = 35cm
The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.
