Answer:
ans: ii) 87° and iii) 60°
Step-by-step explanation:
ii)
y° = 180° - ( 56° + 37°)
missing angle on triangle is alternate angle of y° so are equal and sum of angles of triangle is 180°
iii)
x° + 2x° = 180°
sum of co interior angles is 180°
You will divide by 2 on each sides then x will be your answer
So x is greater than or equal to 4
I believe it is m < 5 I could be wrong sorry.
Let the amount he invested in the 5% rate be x and the one in the 7.5% rate be y, then
x + y = 10000 . . . (1)
0.05x = 0.075y . . . (2)
From (2), x = 0.075y/0.05 = 1.5y . . . (3)
Putting (3) into (1) gives
1.5y + y = 10000
2.5y = 10000
y = 10000/2.5 = 4000
x = 1.5(4000) = 6000
Therefore, he invested $6,000 in the secure GIC at 5% and $4,000 in the mutual fund.
