Answer 1

Answer:

Angle AMD = 90°

Step-by-step explanation:

Consider ∆ AMB ,

AM is the hypotenuse

BM is the base = 4 cm

AB is the Altitude = 6 cm

AM^2 = AB^2 + BM^2

AM ^2 = 6^2 + 4^2

AM ^2 = 36+16

AM ^2 = 52

AM = 7.2 cm

Now consider ∆ MCD ,

MD is the hypotenuse

CD is the Altitude = 2 cm

MC is the base = 3 cm

MD^2 = CD^2+ MC^2

MD^2 =2^2 + 3^2

MD^2 =4+9

MD ^2= 13

MD = 3.6 cm

7.2 ^2 + 3.6^2

51.84 + 12.96

= 64.8

√64.8=8.04

~ 8

Angle AMD = 90°
