In a right-angled triangle smallest angle : largest angle = 3:5
Work out the three angles of the triangle.
Your final line should be written like this. The angles are ... , ... , ...

Step-by-step explanation:

Given

Triangle is right-angled

The ratio of smallest and largest angle is 3:5

let the angles be 3x and 5x

In a right-angled triangle, the largest angle is

3x is the smallest angle. Its complementary angle is

Complementary angle is

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
