In ΔEFG and ΔYXZ, m∠F ≅ m∠X and m∠E ≅ m∠Y. If m∠E = 62° and m∠X = 80°, what is the measure of ∠Y?
1 answer:
Answer:
C. 80°
Step-by-step explanation:
I believe it's 80 l
: If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
In this problem
Triangles EFG and YXZ are similar by AA Similarity Theorem
Because
m∠F ≅ m∠X and m∠E ≅ m∠Y
Remember that in a triangle the sum of the interior angles must be equal to 180 degrees
so
m∠G ≅ m∠Z
we have
m∠E = 62°
m∠X = 80°
Remember that
m∠F ≅ m∠X
therefore
m\angle F = 80^om∠F=80o

because i know how to do it
Logₐx=b means aᵇ=x
reverse
aᵇ=x means logₐx=b

Answer:
JL = 54
Step-by-step explanation:
JL = JK + KL
JK = KL
8x+11 =14x-1
12 = 6x
x = 2
substitute for x:
8(2)+11 + 14(2)-1 = JL
JL = 16+11+28-1
JL = 54
