An angle measures 51.4° less than the measure of its complementary angle. What is the measure of each angle?
kap26 [50]

Answer:

70.7 deg, 19.3 deg

Step-by-step explanation:

The sum of the measures of complementary angles is 90 deg.

One angle measures x.

The other angles measures 51.4 deg less than x, or x - 51.4.

The sum of their measures equals 90.

x + x - 51.4 = 90

2x - 51.4 = 90

2x = 141.4

x = 70.7

x - 51.4 = 70.7 - 51.4 = 19.3

Answer: 70.7 deg, 19.3 deg

Solve the following equation. x/3 - 4 = 10
erma4kov [3.2K]

Answer: x=42


Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- Solve for x.

- Add 10 and 4.

- Multiply the sum of 10 and 4 by 3. You must move it from the left member to the right member. Then, if  3 is dividing x, this will multiply the sum of 10 and 4. So, you have:

x/3=10+4\\x/3=14\\x=42

Therefore, you obtain that the value of x is 42
