Select the correct answer.
makvit [3.9K]

Answer:

<h3>64°</h3>

Step-by-step explanation:

y = 52° ( Opposite Angles )

y + 2x = 180° ( Interior Angles )

y + 2x =  {180}^{o}  \\  {52}^{o}  + 2x =  {180}^{o}  \\ 2x =  {180}^{o}  -  {52}^{o}  \\ 2x =  {128}^{o}  \\ x =  \frac{ {128}^{o} }{2} \\ x =  {64}^{o}  \\

Each sheep has 4 legs and each chicken has 2 legs.if a farm boy counts 50 heads and 130 feet, how many sheep are there
slavikrds [6]

Answer:

15 sheep

Step-by-step explanation:

1 leg = 1 foot

1 head = 1 animal

Suppose all the animals are chickens:

50 × 2 = 100

130 - 100 = 30

4 - 2 = 2

30 ÷ 2 = 15

Hence, there are 15 sheep.

<h3>Answer: Choice 2)  sin(B) = cos(90-B)</h3>

Explanation:

The rule is that

sin(A) = cos(B)

if and only if A+B = 90.

Solving for A gets A = 90-B

So we end up with

sin(90-B) = cos(B)

which is the same as

cos(B) = sin(90-B)
