Question is Incomplete; Complete question is given below.

Which expression is equivalent to (3x-5y)+(x+2y)?

1. 4x-7y

2. 4x-3y

3. 4x+3y

4. 4x+7y

2.

Step-by-step explanation:

Given:

We need to simplify the given expression;

Solution on simplifying the given expression we get;

First we will apply distributive property to remove the parenthesis we get;

Now Combining the like terms together we get;

Now adding and subtracting like terms we get;

Hence the equivalent expression for given expression is .

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
