We know that the right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees.

To find x:

(10x - 20) + (6x + 8) = 180

16x - 12 = 180

+12 +12

16x = 192

----- -----

16 16

x = 12

Check:

(10(12) - 20) + (6(12) + 8) = 180

(120 - 20) + (72 + 8) = 180

100 + 80 = 180

180 = 180

Angle (10x - 20):

(10(12) - 20)

(120 - 20)

100

Angle (6x + 8):

(6(12) + 8)

(72 + 8)

"If 5 is decreased from double Joe's weight, the result is 230. What is Joe's weight?" 30

Gala2k [10]

Answer:

117.5 or 235/2

Step-by-step explanation:

We can set up an equation for this problem:

Lets Joe's weight be x

then:

2x -5 = 230

therefore:

2x = 235

x = 117.5 or 235/2
