Answer:
145°
Step-by-step explanation:
There are a couple of ways you can get there:
1. ∠ACB is a right angle, 90°. Hence, ∠BAC is the complement of ∠ABC, so is ...
... ∠BAC = 90° -∠ABC = 90° -55° = 35°
Then, ∠BAC and ∠BAD are a linear pair, so total 180°. That makes ∠BAD the supplement of ∠BAC, so ...
... ∠BAD = 180° -35° = 145°
2. ∠BAD is the exterior angle at A for the triangle ABC. It will have a measure that is the sum of the opposite interior angles: given ∠ABC = 55° and right angle ACB = 90°.
... ∠BAD = 55° +90° = 145°
Answer:
Find like terms:
5x and 2x are like terms,
as well as:
42 and 1
do the math per usual but with the like terms:
5x - 2x = 3x
42 -1 = 41
Therefore your answer is:
(3x - 41)
(hope this helps)
5 because 4x5 = 20 and also 3x6= 18 but add another because 18 dont fill the pounds of plaster
