6 0

The complement is what adds to an angle to get 90 degrees

so

x is 25 mroe than 4 times y
x+y=90

x=25+4y
sub 25+4y for x

25+4y+y=90
25+5y=90
minus 25 both sides
5y=65
divide both sides by 5
y=13

sub back
x+y=80
x+13=90
x=77 degrees

17=y 73=x because compliments equal 90

Mallory works 20 hours a week as a website designer and earns $42.50 per hour. If Mallory saves

AleksandrR [38]

If Mallory makes $42.50 per hour and she works 20 hours a week, we multiple those two and we get:

42.5 * 20 = 850

So she earns $850 per week.

Mallory saves half of that amount she would have $425 per week.

In 4 weeks she would have:

425 * 4 = 1700

Mallory will save $1,700 in four weeks.

In right-angled ∆ ABC, ∟B=90⁰. ∆ ABC is in the first and second quadrant on the graph paper. The coordinates of the points A and

Musya8 [376]

Answer:

The given coordinates of the points A and C of the right triangle ABC are (2, 5) and (-2, 3) respectively

The possible pairs of the coordinates of the point B are found as follows;

1) Draw a horizontal line from the point C to the right and a vertical line down from the point A to get the point B at (2, 3) which is the point of the perpendicular intersection of the two constructed lines above

2) Draw a vertical line from the point C upwards and a horizontal line to the left from the point A to get the point B at (-2, 5) which is the point of the perpendicular intersection of the two newly constructed lines here
