Can i have some ? i don't know how to do question e.

see explanation

Step-by-step explanation:

Using the exact trigonometric values

cos30° = , sin30° = and tan45° = 1

Let the point where the segment from C meets AB be D, then

Using ΔBCD

cos30° = = and

= ( cross- multiply )

2BD = x ( divide both sides by 2 )

BD = x ←

sin30° = = and

= ( cross- multiply )

2CD = x ( divide both sides by 2 )

CD = x

Using ΔACD

tan45° = = = = 1 , hence

AD = x ←

Hence

AB = BD + AD = x + x = ( ) x

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

r and t.

both are 64 degrees.
