Answer 1

To find the size of each angle in a triangle given a ratio, divide the sum of the ratios by the total ratio and multiply each angle's ratio by the total sum of the angles!

Step-by-step explanation:

To find the size of each angle in a triangle, we need to divide the sum of the angles by the total ratio. In this case, the sum of the ratios is 6 + 5 + 7 = 18. To find the size of each angle, we multiply the ratio of each angle by the total sum of the angles divided by the total ratio. For the first angle, we have (6/18) * 180° = 60°. For the second angle, we have (5/18) * 180° = 50°. And for the third angle, we have (7/18) * 180° = 70°. Therefore, the size of each angle in the triangle is 60°, 50°, and 70°.
