What is the value of x? Enter your answer in the box.
Radda [10]

Answer:

x=47

Step-by-step explanation:

We can use the triangle bisector theorem

TK             TV

----------- = -----------

YK               YV

Substituting what we know

87.5            77

----------- = -----------

x-22               22

Using cross products

87.5 * 22 = 77 *(x-22)

Distribute

1925  =77x - 1694

Add 1694 to each side

1925 + 1694  =77x - 1694+1694

3619 = 77x

Divide by 77

3619/77 = 77x/77

47=x

an isosceles triangle has angle measures of 55, 55, and 70. the side across the 70 degree angle is 10 inches long. how long are
Shtirlitz [24]

Answer:

The other sides of triangles are 8.72 in and 8.72 in

Step-by-step explanation:

 In a triangle ABC. Please find the attachment for figure.

\angle A=70^{\circ}

\angle B=\angle C=55^{\circ}

Side BC=a = 10 in

Using sine law of trigonometry,

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

Substitute the given value into formula.

\dfrac{10}{\sin 70}=\dfrac{b}{\sin 55}=\dfrac{c}{\sin 55}

\dfrac{10}{\sin 70}=\dfrac{b}{\sin 55}

Cross multiply and we get

b=\sin 55\times \dfrac{10}{\sin 70}

b=8.72 in

It is a isosceles triangle. Therefore, b=c=8.72 in

Hence, The other sides of triangles are 8.72 in and 8.72 in
