Answer:

(A) 24 and 66

Step-by-step explanation

Complementary angles add up to 90 degrees

Supplementary angles add up to 180 degrees

(A) 24 + 60 = 90

These 2 angles sum to 90, so therefore they are complementary

(B) 56 + 124 = 180

These 2 angles sum to 180, so they are supplementary, not complementary

(C) 34 + 66 = 100; 34 + 56 = 90

While 34 and 56 sum to 90 degrees, 34 and 66 sum to 100, so this answer does not satisfy the question

(D) 56 + 124 = 180; 66 + 114 = 180

Both of these angle pairs are supplementary, so they do not satisfy the answer to the question

Otrada [13]
\bf 43\div 6\frac{2}{3}\implies \cfrac{46}{6\frac{2}{3}}\implies \cfrac{\frac{46}{1}}{\frac{6\cdot 3+2}{3}}\implies \cfrac{\frac{46}{1}}{\frac{20}{3}} \implies \cfrac{46}{1}\cdot \cfrac{3}{20}\implies \cfrac{69}{10}

13 = 2f + 5<br> i don't know how to solve this
TEA [102]
<span>Simplifying 13 = 2f + 5
 Reorder the terms: 13 = 5 + 2f
 Solving 13 = 5 + 2f
 Solving for variable 'f'.
 Move all terms containing f to the left, all other terms to the right.
 Add '-2f' to each side of the equation. 13 + -2f = 5 + 2f + -2f
 Combine like terms: 2f + -2f = 0 13 + -2f = 5 + 0 13 + -2f = 5
 Add '-13' to each side of the equation. 13 + -13 + -2f = 5 + -13
 Combine like terms: 13 + -13 = 0 0 + -2f = 5 + -13 -2f = 5 + -13
 Combine like terms: 5 + -13 = -8 -2f = -8
  Divide each side by '-2'. f = 4
 Simplifying f = 4

SO, f = 4

13 = 2 </span>× 4 + 5<span>
