change 10 into a fraction and get 10/1 and then turn 2 1/2 into a fraction which is 5/2 and then multiply 10/1 by 2/5 because you need the reciprocal of 5/2 and get 20/5 which is 4.
Answer:
Angle X is 122°
Step-by-step explanation:
Because it's a 180° line (supplementary angle thm):
180°-58°=122°
Answer:
Option D. DE/DF
Step-by-step explanation:
The following data were obtained from the question:
Opposite = DE
Hypothenus = DF
Adjacent = EF
Sin θ =.?
From trigonometrical operations,
Sin θ = Opposite/Hypothenus.
With the above information, we can find Sin θ as follow:
Sin θ = Opposite/Hypothenus.
Sin θ = DE/DF.
11x + 12(11x + 1) = 12
11x + 132x + 12 = 12
143x = 0
x = 0
y = 11x + 1
y = 11(0) + 1
y = 1 <==
