No Spams Need A Well Explained Ans If U Don't Know Stay Out Of The Question

Answers

Answer 1

The three inside angles need to equal 170 when added together.

When two sides are the same which is shown by the little lines through the sides the two bottom angles are the same.

1. X = 170-80-80 = 20

2. X = 180-75-75 = 30

3. X = 180-70 = 110/2 = 55

Answer 2

Step-by-step explanation:

1) x+80°+80°=180°

x=180°-160°

x=20°.

2) as it is a isosceles triangle, y =75°.

x+75°+75°=180°

x=180°-150°

x=30°.

3) 2x+70°=180°

2x=110°

x=55°.

hope all these helps you.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

The given expression is

csc² (x) - 2csc(x) cot(x) + cot² (x) = tan² (x/2)

Proceed LHS

csc² (x) - 2csc(x) cot(x) + cot² (x)

⇒ (1/sin²(x) ) - 2(1/sin(x) )(cos(x)/sin(x)) +  (cos(x)/sin(x))²

⇒ (1 - 2cos(x) +  cos(x)²)/sin(x)²

⇒ (1 - 2cos(x) +  cos(x)²)/sin(x)²

⇒ (1 - cos(x))²/sin(x)²

⇒ (1 - cos(x))²/sin(x)²+

⇒ [(1 - cos(x))/sin(x)]²                        [ since tan(x/2) =(1 - cos(x))/sin(x)]

⇒ [ tan(x/2) ]²

⇒ tan²(x/2)   = RHS

Hence proved.

You go to Ihop and order two servings of pancakes and a
-cup of coffee. The cost of the coffee is $2.00. You leave a
20% tip. The total bill is $14.40. How much does one serving
of pancakes cost?

Answers

Answer: $4.76

To find the answer you need to find out the total before the 20% tips to find this you need to subtract 14.40 and 20% which = $11.52.If the coffee was $2 you also need to subtract that so the equation would be (11.52-2.00=9.52).Lastly the question is asking you for the price of one serving of pancakes but we have the answer for 2 which is $9.52.To find the price of of 1 serving you need to divide $9.52 by 2 = $4.76.So your answer is $4.76 for 1 serving of pancakes.

The width of a rectangle is 3 yards less than its length. The perimeter is 130 yards. Find the length and width of the rectangle.

Answers

2(L-3)+2L=130
2L-6+2L=130
4L=136
L=34 W =31

Answer:

Length = 34 yards

Width = 31 yards

Step-by-step explanation:

Perimeter = 2(l + w), where l = length, and w = width

We know that w, is l - 3

130 = 2(l + l - 3)

130 = 4l - 6

136 = 4l

l = 34

Width is 3 less than 34, or 31
