Answer:
1: 36° 2: 122° 3: 122° 4: 38°
Step-by-step explanation:
First start out by getting 2 and 3. so 58+angle 3 has to sum to 180° since they are supplementary and are a straight line. So 180-58=122. Angle 2 is the same since theyre vertical. then since a triangle has 180° total, you subtract from 180 to find the final angle measurement.
Answer:
the answerto this is 18.02.
407 over 5 but it also has to be simplified
Answer:
405 
Step-by-step explanation:
Area of a triangle = 
Base * Height
* 30* 27 = 405
8 times 2 is 16 and 12 times 3 is 36. So 16 plus 36 is 52
