Answer:

r = 4.2 cm; d = 8.4 cm

Step-by-step explanation:

The radius is the distance from the centre of the circle to the circumference.

r = 4.2 cm

The diameter is the length of a straight line that passes through the centre with each end at the circumference.

d = 2r = 2 × 4.2 cm = 8.4 cm

b 10 yd  1 ft  2 in

c  99 yd

d.  4840 sq  yd  7 sq ft  119 sq in  

Step-by-step explanation:

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


97 yd   6ft

+2yd   - 6ft

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

99 yd


d. 4,839 sq. yd. 8 sq. ft. 139 sq. in.

                      + 7 sq. ft. 124 sq. in.

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

  4839  sq yd  15 sq ft   263 sq in

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

WILL GIVE BRAINLIST please help I beg ​
Rainbow [258]

Answer:

96°

Step-by-step explanation:

An angle formed by a chord and a tangent that intersect on a circle is half the measure of the intercepted arc.

x = 168/2 = 84°

A straight angle is 180 degrees

y = 180 - x = 180 - 84 = 96°
