Math Problem Statement
Solution
The image contains a problem involving two geometric shapes with angles labeled, asking to find the missing values.
Let's break it down:
The task asks to "Find the values of x in the given figures. Show your solution completely." Both figures represent quadrilaterals with different sets of angles, where one or more angles are unknown and labeled as x.
-
First figure:
- It is a quadrilateral.
- Angles: 85°, 105°, 65°, and x.
- The sum of all angles in a quadrilateral is always 360°.
The equation becomes: Solving for x:
-
Second figure:
- It is also a quadrilateral.
- Angles: 85°, 70°, 150°, and x.
- Similarly, the sum of all angles in this quadrilateral is 360°.
The equation becomes: Solving for x:
Now, let me calculate the values for x in both cases.The missing angle values for the quadrilaterals are:
- In the first figure, .
- In the second figure, .
