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
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:

Therefore, you obtain that the value of x is 42
If you want a then the answer will be
a = 8
Answer:
Set up a proportion ,
80/x 9/100
9 is over 100 because it is a percent and 100% is the highest %.
doing a proportion you cross multiply getting you..
9x =80 x 100
9x= 800
divide by 9 on both sides
that determines your answer
you try !
