Let the angle be x.  The complement of this angle would then be 90-x.

We are told that x is 10 more than 90-x, or       x is 90-x+10, or x= 100 - x.

If x = 100 - x, then 2x = 100, and x = 50.

Check:  If one angle is 50 degrees, the complement is 90-50, or 40 degrees.

Are 50 and 40 complementary?  Yes.  They add up to 90.  Is 50 10 more than 40?  Yes.

The measurements of these two angles are 40 and 50 degrees.

Identify an equation in point slope form for the line parallel to y=1/2x-7 that passes through (-3,-2)
ANTONII [103]

Answer:

Step-by-step explanation:

The point slope form of a straight line is expressed as

y - y1 = m(x - x1)

Where

m represents slope of the line

y1 represents the initial value of y

x1 represents the initial value of x

If two lines are parallel, it means that they have the same slope. From the equation of the given line, slope = 1/2

Therefore,

m = 1/2

x1 = - 3

y1 = - 2

Substituting into the point slope equation, it becomes

y - - 2 = 1/2(x - - 3)

y + 2 = 1/2(x + 3)

The equation is

y + 2 = 1/2(x + 3)

Write the equation for a line that passes through the point (-8,2) and is parallel to 5x-4y=4. Enter your equation in slope inte
Lana71 [14]

Answer:

y = 5/4x + 12

Step-by-step explanation:

5x - 4y = 4

-4y = -5x + 4

y = (-5x + 4)/-4

y = 5/4x - 1

Parallel Slope ---> m = 5/4

(-8, 2)

y = mx + b

2 = 5/4(-8) + b

2 = 5 * -2 + b

2 = -10 + b

12 = b

b = 12

y = 5/4x + 12      <---- This is the answer

Hope this helps!
