Answer:
Angle 3= 135
Step-by-step explanation:
Angle 3=Angle 1 because they are corresponding angles meaning they are equal and on the same side of the traversal.
Hope this helped and the answer was right in the question
Answer:
17.5
Step-by-step explanation:
Those angles are less than 90° so they would be acute angles
(-2,6)
for example
x+1/2y=1
the ordered pair i will use is the first one. (-2, 6)
so
(-2) + 1/2(6)=1
from there it is a simple add/subtract and multiply/divide math problem.
1/2(6)=3
so
(-2) + 3 = 1
yes this ordered pair works for the solution meaning it is the answer.
If you have
2 KNOWN sides & 1 Angle ;
Use Cosine Rule
If you have 3 KNOWN sides,
Also Cosine Rule
If you have
2 KNOWN angles & 1 side,
Use SINE rule
If it's a right-angled triangle, use SOH CAH TOA
Hopefully this helps
