You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;

tan 35° = opposite/adjacent

tan 35° = AB/BC

tan 35° = AB/100

AB = 100tan35°

AB = 100 * 0.7002

AB = 70.02m

Hence the distance across a lake between A and B is approximately 70m

Bess [88]

Answer:

The equation to describe the situation is $p-3=17.$

And, the total weight of the basket of apples was 20 pounds.

Step-by-step explanation:

The question is incomplete so, the complete question is below:

Liang bought a basket of apples to make pies for her friends. The basket of apples weighed p pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies. Write an equation to describe this situation. What was the total weight of the basket of apples?

Now, to write an equation to describe the situation. And to find the total weight of the basket of apples.

So, the basket of apples total weighed = $p\ pounds.$

Liang ate apples weighed = 3 pounds.

And the apples left for the pies weighed = 17 pounds.

Now, to write an equation describing the situation:

$p-3=17.$

Thus, the equation is $p-3=17.$

Now, to get the total weight of the basket of apples:

$p-3=17\\\\Adding\ both\ sides\ by\ 3\ we\ get:\\\\p=20$

Hence, the basket of apples total weighed = 20 pounds.

Therefore, the equation to describe the situation is $p-3=17.$

And, the total weight of the basket of apples was 20 pounds.
