This is the answer to your problem x+y=12x=−18
Turn both mixed fractions into improper fractions
2 3/5 = 13/5
1 4/7 = 11/7
now multiply the improper fractions
13/5 x 11/7
143/35 or 4 3/35
1. Suppose that BC is hypotenuse, then by Pythagorean theorem:
.
2. If BC is not hypotenuse, then BC is a leg and AC is hypotenuse (because AC>AB). Hence by Pythagorean theorem:
.
Answer:
complementary angles
Step-by-step explanation:
That square drawn by the vertex of those angles indicates that the angle formed by the vertical ray pointing up and the horizontal ray pointing right is a right angle. A right angle measures 90 degrees. The measures of the angles measuring x and 71 add up to 90 degrees.
Definition:
Complementary angles are two angles whose measures have a sum of 90 degrees.
The angles measuring x and 71 are complementary angles.
