Answer:
30 degrees
Step-by-step explanation:
Since we know that all triangles equal 180 degrees, we can add the 2 given angles and subtract that from 180 to find the remaining angle.
90+60=150
180-150=30 degrees
Answer:
4 (a.)
Step-by-step explanation:
The x line has to be under 7 and 6 is too close to 7, therefore 4 is the answer
6. x = 16; it's a scalene triangle
7. x = 45; it's a right triangle.
