Answer:

80°

Step-by-step explanation:

The sum of the angles of a triangle is always 180°.

∴ 2x + 3x + 5x = 180°

                  10x = 180°

                     x = 180 / 10

                     x = 18

The biggest angle = 5x

                              = 5 * 18

                              = 90°

german

yes sure, i learned this before so

1. a. make a proportion here, of percentage. \frac{225}{250} =\frac{x}{100} if you cross multiply and divide you get 90%.

1. b. obviously the empty seats would be 10%.

2. a. proportion again, \frac{0.90}{6.00} =\frac{x}{100} cross multiply then divide you ge 15%

3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5
