Excuse me is that a statement or a question because you do not make it sound like one.
Triangle X: 4/5=0.8
Triangle Y: 6/7.5=0.8
(Select the triangles with legs at a ratio of 0.8)
A: 8/10=0.8
B: 3/3.75=0.8
C: 10/12=0.8333333333
D: 12/15=0.8
A, B, and D
I must add though, the wording of this question is very bad.
Answer:
y = 5
Step-by-step explanation:
The 3 interior angles of a triangle sum to 180°
Sum the 3 given angles and equate to 180
100 + 4y + 25 + 3y + 20 = 180 ← simplify left side
7y + 145 = 180 ( subtract 145 from both sides )
7y = 35 ( divide both sides by 7 )
y = 5
