Answer:
a = 17
Step-by-step explanation:
In the picture.
I hope that it's a clear solution.
That is adjacent and huptonuse
soh cah toah
so that is cos
cos(x)=15/21
so tehrfor
cos⁻¹(15/21)=x
where cos⁻¹ means inverse not 1/cos
use your calculator to evaluate cos⁻¹(15/21) in degrees
it is about 44.4153 degres, rounded to 44 degrees
Step-by-step explanation:
the picture isn't realistic but mathematically it's:
1) = 121°
2) = 59°
Answer:
1 and 8 are alternate exterior
8 and 5 are corresponding
3 and 2 are vertical
6 and 3 are alternate interior
14:12
21:18
28:24
That should be the answer
