I need help I’m stuck

Check the picture below, make sure your calculator is in Degree mode.

Step-by-step explanation:

Triangle ABC is a right angle triangle.

From the given right angle triangle,

AB represents the hypotenuse of the right angle triangle.

With m∠A as the reference angle,

AC represents the adjacent side of the right angle triangle.

BC represents the opposite side of the right angle triangle.

To determine AB, we would apply

the cosine trigonometric ratio.

Cos θ, = adjacent side/hypotenuse. Therefore,

Cos 25 = 4/AB

Cross multiplying, it becomes

ABCos 25 = 4

AB = 4/Cos25 = 4/0.9063

AB = 4.41 to the nearest hundredth.

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
