Answer:

x = 20

Step-by-step explanation:

The two angles are complementary angles, which means they add to 90 degrees

2x+7 + 43 = 90

Combine like terms

2x+50 = 90

Subtract 50 from each side

2x+50-50 = 90-50

2x = 40

Divide each side by 2

2x/2 = 40/2

x = 20

How to divide fractions
Tanzania [10]

Answer:

Step-by-step explanation:

When dividing fractions, I use a method called Keep Change Flip. Let's use the example 1/2 divided by 3/4 as an example. First, you have to keep the first fraction the same. This is what you currently have: 1/2 / 3/4. Next, you have to change the divison sign into a multiplication symbol. Now, this is what it should look like: 1/2 x 3/4. Then, you have to flip the fraction 3/4 into 4/3. Now, you have 1/2 x 4/3. Multiply the fraction. If you don't know how to, multiply numerator by numerator, denominator by denominator. You should get 4/6. However, this isn't your final answer. You can simplify this by dividing by 2 to get 2/3. So, your answer is 2/3. Hope this helped you and let me know if you need more help! :D
