Answer:
5 and 85 degrees
Step-by-step explanation:
Ok, so if 2 angles are complementary, that means when put together they equal 90 degrees.
So, let's say one angle is a.
This means the bigger angle would be 17 times the smaller angle, or 17a.
Now let's make an equation:
a + 17a = 90
Now, we have to combine the like terms:
18a = 90
Now in order to find the smaller angle, we just have to divide by 5:
a = 5
This means that the smaller angle is 5 degrees, but because the bigger angle is 17 times the size, we just multiply 5 and 17 together to get 85 degrees.
Hope this helps :)

Simplify = 10+2⋅x
Answer:
the right answer is:
- (A)

Step-by-step explanation:
You take the equations that the exercise give you:
- x + y = 4
- x - y = a
Now you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:
3. y = x - a
And now, you'll replace this third equation in the equation you didn't take (the first in this case).
- x + y = 4
- x + (x - a) = 4
- x + x - a = 4
Add the x variables:
- 2x - a = 4
- 2x = 4 + a
- x = (4 + a) / 2
That's the answer of the exercise, but you can represent this in this form:
- x = (4 + a) / 2 ↔

- x = (4 + a) / 2 ↔

By this reason, the right answer is <u> </u>
