Answer:

39.9

Step-by-step explanation:

a/sinA = c/sinC

a/sin(77) = 16/sin(23)

a = sin(77) × 16/sin(23)

a = 39.89935764

Please answer and explain for brainlest!!​
satela [25.4K]

Answer:

B. 45

Step-by-step explanation:

To solve for angle A, we need to find the value of x. First, we need to find the interior angles of the triangle. We already know 2 of them, x+57 and 63+x but we need the third one. We can do that by subtracting 96 from 180 which is 84.

So now that we have the three interior angles of the triangle, we can make an equation. We already know that the sum of interior angles of a triangle is 180.

84+(x+57)+(63+x) = 180

Simplifying, we get:

204+2x=180

2x = -24

x=-12

Plugging x = -12 into x+57 gives 45 degrees. So, the answer is B.

Alberto ran a race at a speed of 9 meters per second. Omar had a 6 meter head start and ran at a speed of 7 meters per second. B
zloy xaker [14]

Answer: Alberto run 27 meters.

Time taken By Alberto=3 seconds


Step-by-step explanation:

Let d be the distance Alberto ran to catch Omar.

Then, distance ran by Omar=x-6

Also, \text{Time}=\frac{\text{Distance}}{\text{Speed}}

Since, both started running at the same time.

Time taken By Alberto=\frac{x}{9}

Time taken By Omar=\frac{x-6}{7}

Now, at the point they meet time taken by both is equal.

\frac{x}{9}=\frac{x-6}{7}\\\Rightarrow\ 7x=9(x-6)\\\Rightarrow7x=9x-54\\\Rightarrow9x-7x=54\\\Rightarrow\ 2x=54\\\Rightarrow\ x=27

Hence, Alberto run 27 meters.

Time taken By Alberto=\frac{27}{9}=3 seconds
