Answer:
(a) 7
(b) 13
(c) 15
(d) 9
Step-by-step explanation:
(a) In RIGHT TRIANGLE ABC
(BC)^2 + (AB)^2 = (AC)^2
(X)^2 + 576 = 625
X = √49
X = 7
BC = 7
(B) Similarly
(X)^2 + (84)^2 = (85)^2
(X)^2 = (85)^2 - (84)^2
(X)^2 = (85 + 84) (85 - 84) USING A^2 - B^2 = (A + B) ( A - B)
(X)^2 = 169
X = √169
X = 13
AB = 13
(C)
(9)^2 + (12)^2 = (X)^2
81 + 144 = (X)^2
X = √225
X = 15
AC = 15
(D)
(X)^2 + (40)^2 = (41)^2
(X)^2 = (41)^2 - (40)^2
(X)^2 = (41 + 40) (41- 40)
(X) ^2 = 81
X = √81
X = 9
AB = 9
Hope you liked the solution . PLEASE mark me as brainliest.
