Find the degree measure of the angle expressed by 11x-6.

Answers

Answer:

Won't it just be 60, because it's an equilateral triangle.

Step-by-step explanation:

60 + 60 = 120

180 - 120 = 60

11x - 6 = 60

11x = 66

x = 66/11

x = 6

Let's substitute.

11(6) - 6 = 66 - 6 = 60

A store purchased a plasma screen TV for $770 and marked it up 150%. During a sale, the store marked it down 20%. What was the discount price on the plasma screen TV?​

Answers

Answer:

1540

Step-by-step explanation:

First find the new price after the markup

The markup is

770 * 150%

770 * 1.5

1155

Add this to the original price

770 + 1155

1925

Now find the discount

1925*20%

1925*.20

385

Subtract this amount from the 1925

1925-385

1540

The final price is 1540

Answer:

Solution given:

cost price [c.p] of TV =$770

MP=c.p+ 150% of c.p=$770+150/100×770=$1925

discount [D]=20%

now

discount amount=D% of MP=20/100×1925=$385 is your answer.

$385 was the discount price on the plasma screen TV.

In the given diagram(see image) , TAX and TBY are tangents to the circle and C is a point on the major arc.

Question :
If <CAX = 65° , <CBY = 76° , Calculate <ATB.​

Answers

Answer:

∠ATB = 102°

Step-by-step explanation:

Since ∠CBY is less than 90°, CB is not a diameter.

I did this in my head so I drew a sketch to show that around about way I did it. sketch attached:

I drew a third line from X to Y that is tangent to the circle at C.

Because each pair of tangent lines to a common point are equal, we have made three isosceles triangles.  

Now we know 2 of the three angles to ΔXYT, 180 - 50 - 28 = 102° for ∠ATB

Answer:

102°

Step-by-step explanation:

Given

∠CAX = 65° , ∠CBY = 76°

To find

∠ATB

Solution

Refer to attached picture

∠CAX= ∠CBA as same arc intercepted ∠CBY = ∠CAB as same arc intercepted

TAX is a straight angle and:

∠TAB = 180° - (∠CAX + ∠CAB) = 180° - (65° + 76°) = 39°

∠TBA = ∠TAB as two tangents intersect at same distance, their opposite angles are therefore same. ΔATB is an isosceles triangle.

∠ATB = 180° - 2*39° = 102°

A string reaches from the top of a 17-foot pole to a point 13 feet from the base of the pole. To the nearest tenth of a foot, how long is the string?

Answers

Answer:

21.4 feets

Step-by-step explanation:

Using Pythagoras rule :

The length of the string:

Hypotenus = sqrt(opposite² + adjacent²)

Length of string = sqrt(17² + 13²)

Length = sqrt(289 + 169)

Length of string = sqrt(458)

Length of string = 21.400

Length = 21.4 feets

Evaluate.0.2 power of 4 =

Answers

Answer:

0.0016

Step-by-step explanation:

The expression 0.2 by the power of 4  when evaluated has a value of 0.0016

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

0.2 by the power of 4

Express as an equation

So, we have

0.2 by the power of 4 = 0.2⁴

When expanded, we have

0.2 by the power of 4 = 0.2 * 0.2 * 0.2 * 0.2

Evaluate the products

This gives

0.2 by the power of 4 = 0.0016

Hence, the solution is 0.0016

Write an equation that could be used to find the value of x using the interior angles of ∆BDC, then solve it.

Answers

Answer:

  x = 16

Step-by-step explanation:

Either or both of the right triangles can be used to find x. Or, triangle ABC could be used. All numbers are assumed to be degrees.

Using ∆ABD

  55 +90 +2x+3 = 180

  2x = 32 . . . . . . subtract 148

  x = 16

Using ∆BCD

  50 +90 +2x+8 = 180

  2x = 32 . . . . . . subtract 148

  x = 16

Using ∆ABC

  55 +(2x +3) +50 +(2x +8) = 180

  4x = 64 . . . . . . . subtract 116

  x = 16
