Answer:
The answer to your question is: 85°
Step-by-step explanation:
Data
m∠ xyz = 2m∠x - 9
m∠w = 38°
Process
∠x = (∠xyz + 9) / 2
∠ y = 180 - ∠xyz
∠w + ∠y + ∠x = 180
Substitution 38 + (180 - ∠xyz) + (∠xyz + 9) / 2 = 180
76 + 360 - 2∠xyz + ∠xyz + 9 = 360
Simplify
85 - 2∠xyz + ∠xyz = 0
85 = ∠ xyz
Put the dot on the 5 and than go down 4 i think this is right but i might be wrong sorry if i am
To simplify a fraction, divide numerator and denominator by
their greatest common factor.
The greatest common factor of 5 and 20 is 5 .
5/20 = 1 / 4
1 = 1 x 10 exponent 0
27.5 = 2.75 x 10 exponent 1
