For number 11 the third angle would be equal X as the second angle is, since the two sides next to the those angles are congruent. Then you would have to set an equation saying that 2x + 38= 180 and then you can just solve for X
we are given
Firstly, we will factor out 16
we can write it as
we can replace it as
now, we can use property of log
we get
.............Answer
Answer:
98°
Step-by-step explanation:
m∠1 = m∠2
5x + 12 = 7x - 16; substitute the given
2x = 28
x = 14
m∠2 + m∠3 = 180; supplementary angles
82 + m∠3 = 180
m∠3 = 180 - 82
m∠3 = 98 degrees
I would have to say that it is the 3rd answer choice due to the right angle that is formed between line C and line A.
