cos A = 3/5
Step-by-step explanation:
SOHCAHTOA
cot A = 1/tan A
tan A = opp/adj
cot A = 1/tan A = adj/opp
cot A = 3/4
adj = 3; opp = 4
adj^2 + opp^2 = hyp^2
3^2 + 4^2 = hyp^2
9 + 16 = hyp^2
hyp = 5
sin A = opp/hyp
sin A = 4/5
cos A = adj/hyp
cos A = 3/5
Answer:
sin A = 4/5
cos A = 3/5
3/36 (8.333%) thats the probability
Hello!
Angles 3 and 1 are vertical angles, and angles 2 and 4 are vertical angles. Vertical angles are congruent by definition, so angle 3 is congruent to angle 1, and angle 2 is congruent to angle 4.
The adjacent angles are supplementary (they add to equal 180 degrees) so you can set up an equation to solve for x.
180 = 2x + x
180 = 3x
60 = x
x = 60
To find the measure if each angle, plug in x as needed.
Angle 4 = x
Angle 4 = 60 degrees
Angle 2 = angle 4
Angle 2 = 60 degrees
Angle 3 = 2x
Angle 3 = 2(60)
Angle 3 = 120
Angle 1 = angle 3
Angle 1 = 120
I hope this helps you.
