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.
Answer:
x = 50
Step-by-step explanation:
Answer:
65
62
Step-by-step explanation:
In inscribed quadrilaterals, opposite angles are supplementary.
First problem:
x + 148 = 180
x = 32
2x + 1 = 65
Second problem:
x + 20 + 3x = 180
x = 40
180 − (2x + 38) = 62
Answer:
it is eather d or b
Step-by-step explanation:
Answer:
106º
Step-by-step explanation:
In an isosceles trapezoid, there are two sets of cungruent angles. Multiply 74*2=148.
All quadrilaterals have interal degrees that add up to 360º. Use 360-148=212 to find the value of remaining angles. Since the angles are congruent, divide by 2.
212/2=106.
Check by adding all angels.
74+74+106+106=360✔️
