Angles a, b, and c are all 60°. A triangle’s angles add up to 180, and if the triangle is equilateral, each angle must be 60 (180/3). Angle d is 120° because b and d form a supplementary angle (180°), so 180-60 is 120. Angle e and f and 30°. Angles c and e form complementary angles (90°), so 90-60=30. For f, if the triangle adds up to 180, 180-120-30 = f. The 120 comes from d and the 30 comes from e. This leaves f as 30.
Answer:
15:20
Step-by-step explanation:
3 + 4 = 7
35 / 7 = 5
5 x 3 = 15
5 x 4 = 20
Therefore the answer is 15:20
If the recipe requires 3/8 cup of sugar per every one cup of flour, and he uses TEN cups of flower, then multiply 3/8 by 10 to meet the supplements.
10/1 * 3/8 = 30/8 = 3 & 6/8 cups = 3 & 3/4 cups.
