Find m< 4 in degrees

m < 4 = 120

Step-by-step explanation:

When two anlges are supplementary, their angle measures add up to 180, apply this knowledge here;

m<3 + m<4 = 180

60 + m<4 = 180

m<4 = 120

120

Step-by-step explanation:

m<3 is 60 and 180-60=120

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
