Find the value of x.

Mathematics
2 answers:

Step-by-step explanation:

The sum of the three angles in a triangle must be 180. Since this triangle has a right angle, we know that it is 90°, so the sum of the remaining two angles must be 90.

We can set up an equation for the two remaining angles to determine the value of x:

(x + 28) + x = 90

2x + 28 = 90

2x = 62

x = 31

Answer:

x = 31

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180 degrees.

x + x + 28 + 90 = 180

2x + 118 = 180

2x = 62

x = 31

Answer:

Step-by-step explanation:

The standard form of a circle's equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius. To convert an equation to standard form, you can always complete the square separately in x and y.
