Answer:
- ∠B and ∠F
- ∠F and ∠E . . . already listed in the problem statement, so may not be considered an "other pair"
Step-by-step explanation:
∠C and ∠F are vertical angles, so are congruent. Then any angle complementary to one of those will also be complementary to the other.
Likewise, ∠B and ∠E are vertical angles and congruent. Any angle complementary to one of them will also be complementary to the other. Here, ∠E and ∠F are listed as complementary, so we know ∠B and ∠F will be also.
k=2(11-k)+14
k=22-2k+14
2k+k=22+14
3k=36
k=36/3
k=12<em></em>
<em>multiply the numbers.</em>
4 x 6 + y = 20
<em>move constant (24) to the right side and change its sign.</em>
24 + y = 20
<em>calculate the difference and you get the answer.</em>
y = 20 - 24
y = -4
So the value of y is -4.
Answer:
Yes. The square root of 49 is 7, which is a rational number.
