If angle p is right angle and angle p and angle q are supplementary then what is angle q
Schach [20]
Right angle (angle p) = 90°

so 90° + q = 180°
subtract 90° from both sides
q = 90°

a.      2 ft. 5 in. +

9 yd. 3 ft. 2 in.

---------------------

9 yd   5ft   7 in

but 3 ft = 1yd

9 yd   5ft   7 in

+1yd   - 3ft

---------------------------

10 yd   2ft  7 in



b. 4 yd. 8 in

+ 6 yd. 6 in.

----------------------

10 yd   14 in

but 12 in = 1ft


10 yd       14 in

     + 1ft   - 12 in

---------------------

10 yd  1 ft  2 in



c. 29 yd. 2 ft. 11 in.

  55 yd. 1 ft. 10 in.

+ 13 yd. 1 ft. 3 in.  

--------------------------

97 yd   4 ft   24 in

12 in = 1ft

24 in = 2ft


97 yd   4 ft   24 in

           +2ft    - 24 in

--------------------------------

97 yd   6ft

3 ft = 1yd

6f = 2yd

12*12 = 144 sq in = 1 sq ft

 4839  sq yd  15 sq ft   263 sq in

                       + 1 sq ft  - 144 sq in

--------------------------------------------------

4839  sq yd  16 sq ft  119 sq in

3ft * 3 ft = 9 sq ft = 1 sq yd

4839  sq yd  16 sq ft  119 sq in

      +1 sq yd  - 9 sq ft

----------------------------------------------

4840 sq  yd  7 sq ft  119 sq in
