Answer:
A. 0.69
Step-by-step explanation:
To find this, apply the cosine theorem:
c²=a²+b² - 2ab * cos(θ)
where c=8, a=7, b=11
Thus, 8² = 7² + 11² - 2*7*11 *cos(θ)
64 = 49 + 121 - 154*cos(θ)
Thus, 64 - 170 = - 154*cos(θ)
- 106/(- 154) = cos(θ)
[[TAG_29]]Therefore, cos(θ) = 0.69[[TAG_30]]

Answer:
The measure of arc GH is 80 degrees.
Step-by-step explanation:
Circles F and J are congruent.
Given that: m∠DFE = 80°
Angle DFE serves as the central angle of circle F.
Arc GH's measurement corresponds with the central angle from Circle J.
Since the two circles are congruent
The measure of arc GH, therefore, is 80 degrees.
Answer:
Joanne might have utilized a rounded figure at a specific decimal point instead of the precise value. When validating her solution with a rounded figure, the outcome may not align precisely. The values, 12.34 and 12.33, are very similar, allowing Joanne to conclude that she correctly solved the multistep equation.
