Questions 1, 2, and 3. Help!

Answers

Answer:

1. 90      2. 130       3. 55

Step-by-step explanation:

Every triangle when you add all the angles will = 180 degrees for this you add the 2 angles that you have and subtract it from 180

1.   35+55+ C = 180

90 = 180

C = 90

2. 25+25+C = 180

50 + C = 180

C = 130

3. 62 + 63 + C = 180

125 + C = 180

C = 55

Answer:

Step-by-step explanation:

sum of all the angles of triangle = 180

1) ∠1 + ∠2 + ∠3 = 180

35 + 55 + ∠3 = 180

90 + ∠3 = 180

       ∠3 = 180 -90

            ∠3 = 90

If one angle is 90, then, it is a right angled triangle.

2) 25 + 25+ ∠3 =180

        50 + ∠3 =180

             ∠3 =180 -50

       ∠3 = 130

If two angles are equal, then it is an isosceles triangle.

3) 62 + 63 + ∠3 =180

             125 +∠3=180

                     ∠3 = 180-125

                     ∠3 = 55

All the angles are different, so it is a scalene triangle

Since 5 is in most of the answers, I´m guessing that 5 is the length of the short leg. The answer is C

Step-by-step explanation:

In SohCahToa, Sine, Cos, and Tan all have a formula. Since your looking for tan, you would find the sides that are opposite and adjacent to the hypotenuse. And since tan is opposite over adjacent, it would be 5 over 12.

Sine=Opposite over Hypotenuse

Cos=Adjacent over Hypotenuse

Tan=Opposite over Adjacent

Answer:

15a² + 21a + 19 = 0

Step-by-step explanation:

Given

(4a + 3)² = (a + 5)(a - 2)

(4a + 3)(4a + 3) = (a + 5)(a - 2 ) ← expand both sides using FOIL

16a² + 24a + 9 = a² + 3a - 10 ( subtract a² + 3a - 10 from both sides )

16a² - a² + 24a - 3a + 9 + 10 = 0 ← collect like terms

What is the value of 16.43 – 1.043

Pls show the work of how you did it

Answers

Answer:

15.387

Explanation:

16.43
- 1.043
————
15.387
Decimals are cool because you can add zeros to the end of them, and they will still be the same number.

16.43 = 16.430

I add the zero to the thousandths place because I am subtracting a number from 16.430 that has a number in the thousandths place. When you line the two numbers up to subtract you want to make sure they have an equal amount of decimal places.

1 6. 4 3 0 <— you now are ready to subtract.
- 1 . 0 4 3 I lined up the numbers in the
—————— ones, tenths, hundredths + Thousandths place. I drop the decimal point down.

Start from the rightmost digit.
You can’t subtract 3 from 0, so you borrow ten from the left.
3-1 =2. Cross out 3 and write 2 above it.
You add 10 to 0. 10+0=10. Cross out 0 and write 10 above it.
You can subtract 3 from 10 now. 10-3=7.

2 10
1 6. 4 3 0 You now have this.
- 1 . 0 4 3
——————
. 7

You can’t subtract 4 from 2, so you borrow from the left again.
4-1=3. Cross out 4 and write 3 above it. 2+10=12. Cross out 2 and write 12 above it.
12 - 4 = 8.
This is what that looks like:

12
3 2 10
1 6. 4 3 0 You now have this.
- 1 . 0 4 3
——————
. 8 7

3 - 0 = 3.
6 - 1= 5.
1 - 0 (as there is no digit in the tenths place) = 1

12
3 2 10
1 6. 4 3 0 You now have this.
- 1 . 0 4 3
——————
1 5. 3 8 7

So 16.43-1.043= 15.387

Given that the formula for density is equal to mass all over the volume.

Dave has $358 in his bank account. He wants to prepay his cell phone bill for the next three months. His monthly cell phone bill is $78. He also needs to pay his electric bill, which is $135. How much money will Dave need to add to his account to cover all his bills?

Answers

Answer:

$11

Step-by-step explanation:

Given data

Total amount=  $358

Monthly cell phone bill= $78

      Bill for the three months = 78*3= $234

      Electtrcilty bill = $135

      Total bills= $234+ $135=$369

Hence, the amount to be added= 369-358 =$11
