Answer 1

Answer:

74 degrees

Step-by-step explanation:

Assuming we have the following

FD = 14

DE = 52

m<F = 90degrees

Required

m<D

DE = hypotenuse

FD = adjacent

Using the SOH CAH TOA identity

Cos m<D = adj/hyp

Cos m<D = 14/52

m<D = arccos(0.2692)

m<D = 74.38

m<D to the nearest degree is 74degrees

Answer:

m < 2 = 45°

Step-by-step explanation:

m < 1 and m < 3 are corresponding angles that lie on the same side of the transversal.  Since they are corresponding angles, then it means that they have the same measure.

Therefore, if m < 1 = 135°, then m < 3 = 135°.

Also, the sum of m < 2 and m < 3 = 180° because they are supplementary angles.

Therefore:

m < 2 + m < 3 = 180°

m < 2 + m < 135° = 180°

m < 2 = 180° - m < 135°

m < 2 = 45°

Answers

Answer:

The first question

cos 30 = 50/x

√3/2 = 50/x

x√3 = 100

x = 100√3/3

x = 57.7350 ≈ 57.74

The second question

sin 45 = x/55

√2/2 = x/55

55√2 = 2x

x = 55√2/2

x = 38.8908 ≈ 38.90

The third question

cos 40 = x/34

x = 34 × 0.7660

x = 26.044

fill in the blanks with <,>,= symbols( -3)+(-19)+6...................(-41)-15+9​

Answers

First we will simplify both equations....#1

[tex]( - 3) + ( - 19) + 6 \\ - 3 + ( - 19) + 6 \\ - 3 - 19 + 6 \\ = - 16[/tex]

#2

[tex]( - 41) - 15 + 9 \\ - 41 - 15 + 9 \\ = - 47[/tex]

Now,

[tex] - 16 > - 47[/tex]

How?

When the number is in negative the smaller number is greater than the greater number.

Answer:

(-3)+(-19)+6 [>] (-41)-15+9

Step-by-step explanation:

(-3)+(-19)+6= -16

and

(-41)-15+9= -47

so, -16 is greater than -47

He has a coupon for $10 off any grooming service. He must pay an 8% sales tax, which is applied to the discounted price, and then added to find the total price. Estimate the total amount Paul paid at the dog groomer.

Answers

Answer:

Well since you didn't provide the initial cost im just going to use 100$ as the initial cost.

the service costs 100 dollars minus the coupon of 10 dollars so 90 plus the sales taxes it is (which is 7.20$) it leaves us with a total of 97.20 saving him 10.80$ if he did not use the coupon

The length of a rectangle is 4ft longer than it’s width. If the perimeter of the rectangle is 68ft, find it’s length and width.

Answers

Answer:

Represent the length and width by L and W. Then L = W + 4.

Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).

Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.

The dimensions of the rectangle are 15 by 19 feet.
