As the total angle is a straight angle (its measure is 180 degrees), the angles GHL and LHK are supplementary angles (their meausres add up to 180 degrees)
to get the measure of angle LHK = 180 - 79 = 101 degrees
I hope that
helps!
A:amount of money invested in the account with 3% simple interest
B: amount of money invested in the account with 4.5% simple interest
a+b=25000 ——>a=25000-b
0.03a+0.045b=900
30a+45b=900000
2a+3b=60000
2(25000-b)+3b=60000
50000-2b+3b=60000
B=10000
A=25000-10000=15000
Cube= 1/6
coin= 1/2
1/2*3= 3/6
3/6+1/6= 4/6
4/6= 2/3
The answer is 4/6 or 2/3
(14,-1) is the answer to the question
