In the diagram, we know that ∠Y and ∠X appear to be similar. We also note the bottom triangle is equal to 180°. So, Y° + 50° + 60° = 180.....Y = 70°
Since Y = 70°, X also is equal to 70°
Answer:
Y+X=50
Y=2X - 43
X=31 Y=19
Step-by-step explanation:
The answer is B.) Y = sec X.
Multiply both sides by x, so:
7x/28=25. then multuply both sides by 28 so:
7x= 700
divide both sides by 7
so x=100
