Calculate the length of the unknown side of this right-angled triangle.
9 cm
8 cm
Answer:
the length of the unknown side of the right angle triangle is 1 cm
Step-by-step explanation:
The computation of the length of the unknown side of the right angle triangle is shown below:
= √9^2 - √8^2
= √81 - √64
= 9 - 8
= 1 cm
Hence, the length of the unknown side of the right angle triangle is 1 cm

The ratio of girls to boys in a swimming club was 2 : 4. There were 14 girls. How many total members were there in the club?
Answer:
42
Step-by-step explanation:
the ratio 2:4 can be reduced to 1:2,
where the number of girls corresponds to the 1 and the number of boys corresponds to the 2.
If there are 14 girls, then there must be 28 boys (14 x 2 = 28).
Now to get the total number we need to add the total number of boys and girls together.
So 14 + 28 = 42
Hope it helps :)
Answer:
32
Step-by-step explanation:
14 + 28 = 32
2 x 7 = 14
4 x 7 = 28

Alma is going to walk through the park from Point A to
Point B
What distance will she walk?
HELPPPPPPPPPPPPPPPPP
Answer:
I think the answer is 200 feet
Step-by-step explanation:
Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then Alma is going to walk through the park from Point A to Point B is 282.84 ft.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
A right-angle triangle has sides with lengths 200 ft and 200 ft.
By Pythagoras theorem, we have
H² = P² + B²
H² = 200² + 200²
H² = 40000 + 40000
H² = 80000
H = 200√2
H = 282.84 ft
Alma is going to walk through the park from Point A to Point B is 282.84 ft.

Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value
Answer:
x = 16°
Step-by-step explanation:
We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°
∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)
∠ACD = x, ∠DCE = 148, ∠ECD = x
substituting the respected values for the angles gives:
x + 148 + x = 180
2x + 148 = 180
subtracting 148 from both sides:
2x + 148 - 148 = 180 - 148
2x = 32
Dividing both sides by 2, to get x:
2x/2 = 32/2
x = 16°
5x^+20x +15=0

6^2-4+1 i dont know if you need to simplify even more but if you do
36-4+1 32+1 31
i hope this helps you!
Answer:
The answer is 9.
Step-by-step explanation:
Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.
1. Plug in X: 3(2)^2 -2(2) + 1
2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1
3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1
4. Addition: -4 + 1 = -3, so it is now 12-3
5. Subtraction: 12-3 = 9, so the answer is 9!

O-4
O-2
O-9
09
Answer:
Step-by-step explanation:
x² + 6x = 8
Coefficient of the x term: 6
Divide it in half: 3
Square it: 3²
Add 3² to both sides of the equation to complete the square and keep the equation balanced:
x² + 6x + 3² = 8 + 3²
(x+3)² = 17
