Since we know that a - 2 will equal 8, it is safe to assume that 8 + 2 = 10. Therefore a=10.
Answer:
x=-5
y=5
Step-by-step explanation:
Explanation is in picture (Where the lines cross is your answer)
Tip: Try using desmo calculator. Where the lines cross is your answer so all you need to do is type in your equations
Answer:
x = 125
Step-by-step explanation:
Ok so we already established that AIA are congruent. So two angles will equal 55 degrees. All angles in a parallelogram add up to 360 degrees, and there are two pairs of matching angles opposite of each other.
So we take the two 55 degree angles and subtract them from 360:
360-110 = 250
Now there are two identical angles left, one of them is x, that equal a total of 250, so divide by two:
250/2
=125 degrees
Answer:
In words, if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the triangles are congruent. If in triangles ABC and DEF, angle A = angle D = right angle, AB = DE (leg), and BC = EF (hypotenuse), then triangle ABC is congruent to triangle DEF.
If you picture the coordinate plane and you have some point (x,y) rotating it full circle: 360° would return it to it's original location (x,y).
