For triangle ABC, angle A=110, angle B=43, and side b=15. Find side c.
vredina [299]

Answer: 10

<u>Step-by-step explanation:</u>

First, find m∠C by using the Triangle Sum Theorem:

∠A + ∠B + ∠C = 180°

110 + 43 + ∠C = 180°

     153   + ∠C = 180°

                ∠C = 27°

Next, Use the Law of Sines to solve for c:

\dfrac{b}{sin\ B}= \dfrac{c}{sin\ C}

\dfrac{15}{sin\ 43}= \dfrac{c}{sin\ 27}

\dfrac{15\ sin\ 27}{sin\ 43}= c

10 = c

Lean wants to giftwrap a present she got for her little brother. how many square inches of giftwrap will be needed to cover a bo
Natalka [10]
Check the picture below.

so.. notice, the box for the gift is really just a rectangular prism, which is really just 6 rectangles stacked up to each other at the edges.

the front and back are two 5x3 rectangles

the left and right are just two 3x7 rectangles

and the top and bottom are just two 5x7 rectangles

so, just get the area of each, sum them up, and that's the area of the rectangular prism and thus of the box, and that's how many in² she will need.

Answer:

  x = 12

Step-by-step explanation:

The square of the length of the tangent segment is equal to the product of lengths from the external common point to the two circle intersections of the secant.

  x^2 = (2)(70+2)

  x^2 = 144

  x = √144

  x = 12

Mamont248 [21]

A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes.

We know the formula , Distance = speed * time

Speed is constant and it is 12. So it  is linear

The function becomes d = 12t, x is the t is the time and d is the distance

At the starting point, t=0  and distance d=0

End point , t=45 min = 0.75 hours and distance = 12 * 0.75 = 9

So domain (t) is {x|0}

Range (d) is {y|0}
