Use What You Already Know To Find A, B, And C.Input Each Value. Then Click Done. HELP ME PLEASE FAST!

Answers

Answer 1

Answer:

Use the "find vertically opposite angle" method.

a = 80°

To find the other angles:

Since the angles equal up to 360 which makes a full circle shape...

360 - 80 - 80 = 200 (B and C)

200 ÷ 2 = 100 (Angle for B and C since they are vertically opposite, hence having the same angle)

b = 100°

c = 100°

2. The following triangle, ∆, has angle measures as shown.
Step 1: What is the measure of angle C? Show your work.
Step 2: What is the value of x? Show your work.

Answers

Answer:

x=29. Angle C= 93

Step-by-step explanation:

3(x+2)= 3x+6.

3x+6+52+35= 3x+93.

180-93=87.

87/3= 29. So that means x=29.

for proof you can do 3(29)+93 and you'll get 180.

For angle C; 3(29+2)= 3x31. 31x3= 93.  

Angle C= 93 degrees.

The length of a garden is 23m, correct to the nearest metre.

Write down the least possible length of the garden.

Answers

Answer:

22.5m

Step-by-step explanation:

Since it's correct to the nearest metre, it has an interval of ± 0.5

Using rounding concepts, it is found that the least possible length of the garden is of 22.5m.

------------------

If the first decimal digit is between 0 and 4, rounding to the nearest integer, the integer part remains the same.If the first decimal digit is between 5 and 9, rounding to the nearest integer, one is added to the integer part.Thus, in the context of this problem, garden lengths between 22.5 and 23.4 are rounded to 23m, and thus, the least possible length of the garden is 22.5m.

Step-by-step explanation:

The first step in factoring is to bring out the greatest common factor. In this case, the GCF between 5m and -15 is 5.

To find out out the expression inside the parenthesis, divide the current expression by the GCF,

(5m-15)/5

m-3

Two airplanes leave the airport at the same time. One plane is flying 700mph at a bearing of N46°W and the other plane is flying 895mph at a bearing of
N43° E. After 3 hours, how far are the planes from one another?

Answers

9514 1404 393

Answer:

  3380 miles

Step-by-step explanation:

The distance separating the planes can be found using the law of cosines. One plane has gone 3×700 = 2100 miles; the other has gone 3×895 = 2685 miles. The angle between their flight paths is 46°+43° = 89°. Then the separation (s) is ...

  s² = 2100² +2685² -2(2100)(2685)cos(89°) = 11,619,225 -11,277,000×0.01745

  s² ≈ 11,422,414.21

  s ≈ √11,422,414.21 ≈ 3379.7

The planes are separated by about 3380 miles after 3 hours.
