2/3+4/9
denominator= 3*9=27
numerator = (18+12)= 30
therefore the answer is 30/27= 10/9
Answer:
∠AMB = 54°
Step-by-step explanation:
2x + (x + 9) = 90°
3x + 9° = 90°
3x = 81°
x = 27°
∠AMB = 2x = 54°
The value of x can be found by adding the two angles and setting them equal to 180 because they are on a straight line.
3h + 18 + 15h = 180
18h + 18 = 180
18h = 162
h = 9
So the value of h is 9
