Answer:
My total savings was = $58.33
Step-by-step explanation:
Given:
12% of my savings was = $7.00
To find my total savings.
Solution:
Let the total savings in dollars be = 
12% of the total savings will be = 
12% of my savings was = $7.00
So, we have:


Solving for
to get my total savings.
Dividing both sides by 0.12

∴ 
Thus, my total savings was = $58.33

Answer:
m∠ADC = 132°
Step-by-step explanation:
From the figure attached,
By applying sine rule in ΔABD,


sin(∠ADB) = 
= 0.74231
m∠ADB = 
= 47.92°
≈ 48°
m∠ADC + m∠ADB = 180° [Linear pair of angles]
m∠ADC + 48° = 180°
m∠ADC = 180° - 48°
m∠ADC = 132°
