Answer:
1 : 51 2 : 39 3 : 90
Step-by-step explanation:
1 : 180(internal angle of triangle) - 90 - 39 =51
2. alternate angles
3. internal angles of rectangle are always 90
5+7+3= 15 is the Area of the figure
If the circumference is 34 Times PI that means that 34 is the diameter.
So that means that you can just divide the diameter by 2 to get the radius (Because the radius is half of the diameter.)
So the answer is the diameter is 34 and the radius is 17
