Question

9. If in a right angled triangle base is 4m. and perpendicular is 3m. the length of hypotenuse is:
a) 5m .
b) 8m. c) 7m. d) 3m.
10. The value of (-1)188 is:​

Answer 1

Answer:

a)5cm

Step-by-step explanation:

By Pythagoras theorem

(hypotenuse)^2 =(base)^2+(perpendicular)^2

h^2=4^2 + 3^2

h^2=16+9

h^2=25

h = 5cm

Answer 2

Answer:

answer of Q. 9  = 5cm

answer of Q. 10= -188

Step-by-step explanation:

acc. to pythagores theorem hypotenuse sq. = base sq. + perpendicular sq.

                                         so,

                                               hypotenuse sq. = sq. of 4 + sq. of 3

                                                                           =  16 + 9

                                                hypotenuse = root of 25

                                                                     = 5 cm

q 10) sol :-         - 1 (188) = -1 multiply 188

                                      = -188
