Answer:
80% decrease
Step-by-step explanation:
A percentage change can be calculated using ...
percent change = ((new value)/(old value) -1) × 100%
= (16/80 -1) × 100%
= -0.80 × 100% = -80%
The minus sign indicates the change was a decrease.

Answer:
b = 8√3 and c = 16
Step-by-step explanation:
<u>Points to remember</u>
If the angles of a right angled triangle with angles are 30°, 60, and 90 the their sides are in the ratio 1 : √3 : 2
<u>To find the unknown side lengths</u>
From the given figure we can see a right angled triangle
Angles are 30°, 60° and 90°
sides are in the ratio 1 : √3 : 2
1 : √3 : 2 = 8 : b : c
b = 8√3 and c = 8 * 2 = 16
Therefore b = 8√3 and c = 16

Distance stretched = 0.4 * 124 = 49.6 cms
converting to meters we divide by 100:-
Answer is 0.496 meters
90 + 20x + 10x = 180
30x = 90
x = 3
