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
Step-by-step explanation:
For this case, the first thing we should do is use the following equation:
x ^ 2 + x-30
Here, we substitute the value of x = 20
We have then:
(20) ^ 2 + (20) -30 = 390 m ^ 2
Answer:
the area of the land when the length of the dentist's office is 20 meters is:
390 m ^ 2
Answer:
47g
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
b and 55° form a right angle = 90° , then
b + 55° = 90° ( subtract 55° from both sides )
b = 35°
The sale price is 30% of the original price (70% reduction). So $156 is 30% of the original price. 10% of the original price is $52, therefore the original price is $520 (100% price).
