Answer:
The answer is correct: radians -1.7pi is -306 °
Answer: 39 degrees
Step-by-step explanation:
Since the triangle is a right angle
The sum of angles in a right angle is 90degrees
51degrees + A= 90 degrees
A= 90degrees - 51 degrees
A=39 degrees
Answer:
Terry initially had £390
Step-by-step explanation:
The ratio of the original amount is 3:7
Let the original amount Terry has be t and the original amount Faye has be f
3/7 = t/f
or simply 3f = 7t ••••••(i)
Terry putting 220 means he now has
t + 220
Faye withdrew 300
He now has f-300
These values are equal
t + 220 = f-300
f = t+220+300
f = t + 520 ••••••(ii)
Put ii into i
3(t + 520) = 7t
3t + 1560 = 7t
7t-3t = 1560
4t = 1560
t = 1560/4
t = 390
