ANSWER:

x = 11

OR

x = - 5

In triangle ABC displayed in the diagram, the value of ( x ) is 11 or - 5.

STEP-BY-STEP EXPLANATION:

In triangle ABC, AB is equivalent to AC. This means that the triangle is an isosceles triangle as two sides are equivalent in length.

Since triangle ABC is an isoceles triangle, the base angles must be equivalent to each other.

( x^2 - 6x )° and 55° are both base angles of the isosceles triangle ABC.

THEREFORE:

x^2 - 6x = 55

x^2 - 6x - 55 = 0

x^2 - 11x + 5x - 55 = 0

x ( x - 11 ) + 5 ( x - 11 ) = 0

( x - 11 ) ( x + 5 ) = 0

Solution No. 1 -

x - 11 = 0

x = 11

Solution No. 2 -

x + 5 = 0

x = - 5

The hypotenuse of a right triangle is 6 inches. if one of the legs is 2 inches, find the degree measure of each angle
miskamm [114]
A and b are the 2 smaller sides, and c = hypotenus; only for right triangles,
Pythagorean Theorem states that:
{c}^{2}  =  {a}^{2}  +  {b}^{2}
given c = 6 in., a = 2 in.
{c}^{2}  =  {a}^{2}  +  {b}^{2}  \\  {6}^{2}  =  {2}^{2}  +  {b}^{2}  \\ {b}^{2} =  {6}^{2}  -  {2}^{2} = 36 - 4   \\ \sqrt{ {b}^{2} }  =  \sqrt{36 - 4}  =  \sqrt{32}
b =  \sqrt{32}   =  \sqrt{16}  \times  \sqrt{2}  = 4 \sqrt{2}  \\ b = 5.66 \: inches
So the three side are 2, 6, and 5.66 inches

Pythagorean theorem is formula we would use:
1.)
c^2=a^2+b^2
c^2=10^2+24^2
c^2=100+576
c^2=676
c= √676
c=26 in

2.)
c^2=7^2+14^2
c^2=49+196
c^2=245
c= √245
c~15.65 cm

A pair of shoes usually sells for $62. if the shoes are 20% off and the sale tax is 5% what is the total price of shoes includin
coldgirl [10]
Given that a pair of shoes has a price of $62, and it is discounted for 20%, so this would mean that $12.4 is discounted to the original price. So the new price would be $49.6. And now, since there is a 5% tax added, $2.48 is added so the new total price would be $52.08. The answer would be option D. Hope this helps.
