Answer:
The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h. Hence, to find the area of a tri-sided polygon, we have to know the base (b) and height (h) of it.

The dimensions of a rectangle are 2x - 5 and 2x - 5. Which expression represents the area of the rectangle in simplest terms?
Answers
Answer:
Step-by-step explanation:
(a - b)² = a² - 2ab +b²
Area of rectangle = length * width
= (2x - 5)(2x -5)
= (2x - 5)²
= (2x)² - 2*(2x)(5) + 5²
= 4x² - 20x + 25

What is the value of 16.43 – 1.043
Pls show the work of how you did it
Answers
15.387
Explanation:
16.43
- 1.043
————
15.387
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

Step-by-step explanation:
Hello, I am no math expert so take this with a grain of salt. Tan=Opposite/Adjacent. Side ON is opposite and side MN is Adjacent. This would mean that the ration would be 5/12. I hope that helped!
Answer:
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

Express the following equation in the form ax^2+bx+c=0:
(4a+3)^2=(a+5)(a−2)
Answers
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
15a² + 21a + 19 = 0

Answer:
17 sq cm
Step-by-step explanation:
i used the formula, A = 1/2h(sum of bases)
A = 1/2(4)(3+5.5)
A = 2(8.5)
A = 17 square cm
A=3+5.5/2 •4
A= 8.5/2 •4
A= 4.25 • 4
A= 18.0625 cm2
99% sure you would round it to 0.5 cm= 5 mm. 99% sure the answer is 18.05 cm sq
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
