Answer with Step-by-step explanation:
We are given that:
tanA = 0.45
tanA= 
= 
⇒
=0.45
⇒
=
⇒
=
⇒ AC= 20
Hence, by pythagoras theorem
AB²=AC²+BC²
AB²=20²+9²
AB²=481
⇒ AB=21.9 units
Hence, the approximate length of AB is:
22 units
Answer:
12 is not a solution.
Step-by-step explanation:
1. Solve for w
8w = 99
w = 99 / 8
w = 12.375
12 is not a solution.
Answer:
26
Step-by-step explanation:
Answer:
Step-by-step explanation:
ok for the first one
the angle measurement of AE which is a straight line is 180
and the Angle measurement of ABC is 50 and because of vertical angles i know that the measurement of FBE is also 50 so all you do it
180 - 50 = 130
so you answer is C
-----------------------------------------------------------------------------------------------------------------------
now for the second one
it would be The corresponding angles Theorem which is option A
