10 Solution:
Step-by-step explanation:
What you're solving for is the value of x.
Whats given in the problem
- The sizes of the angles of a triangle are (x-35)°, (x-25)°, and (1/2 x -10)°
- The sum of the interior angles of a triangle is 180°
Step 1
Form the equation using the fact that the sum of the interior angles of a triangle is 180°
Step 2
Solve the equation for x
Solution
The value of x is 100
11 Solution:
The measures of the angles are m<ABC=104° and m<CBD=76°
