Answer:
A = 73.33
B = 53.33
C = 53.33
Step-by-step explanation:
Mathematically, adding the 3 angles would equal 180
Thus;
A + B + C = 180 •••••(i)
Since B and C are congruent, that means they are equal ( we are looking at isosceles triangle)
B = C •••••••••(ii)
Lastly;
B = A -20 ••••••••(iii)
Make a substitution in equation 1;
A + A -20 + A -20 = 180
Since B = C ; C also is A-20
3A -40 = 180
3A = 220
A = 220/3 = 73.33
B = C = A -20 = 73.33 -20 = 53.33
The answer to the equation is 2.5
Answer: $1150
Step-by-step explanation:
Simple interest is calculated as:
= Principal × Rate × Time
where,
Principal = $2000
Rate = 5.75%
Time = 10
Interest = 2000 × 5.75% × 10
= 2000 × 0.0575 × 10
= 1150
The amount earned will be $1150.
