Answer:

∠AMB = 54°

Step-by-step explanation:

2x + (x + 9) = 90°

3x + 9° = 90°

3x = 81°

x = 27°

∠AMB = 2x = 54°

Answer:

angle AMB is  54

Step-by-step explanation:

2x+ x+9= 90

simplify and get 27

I put 90 in RHS Because The total equals to 90.

if you want to check your work, Do this-

we have the value of x which is 27

so substitute the values and angle AMB will be 54.

Angle BMC will be 36

add them and should get 90.
