Answer:

Step-by-step explanation:

its easy it is trigonometry it isa right angled triangle so for

(i) apply pythogorus thorem

Pythagoras theorem states that “In a right-angled triangle,  the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°. The sides of a right triangle (say x, y and z) which have positive integer values, when squared, are put into an equation, also called a Pythagorean triple.

Perpendicular2 + Base2 = Hypotenuse2

so,

5square -3 square = xsquare

suare root of 5square -3 square = x

x=root of 25-9= root 16

x= 4

(ii)Hypotenuse2 = Perpendicular2 + Base2  

c2 = a2 + b2

so to find hypotenuse

5 square + 12square =x square

x= root of 5 square + 12square

x=root of 25+144

x= root of 169

x=13
