Answer:
x = 12
Step-by-step explanation:
This is a supplementary angle so the right side is equal to 90°. This means the other side must also equal 90°
So subtract 20° from 90° and you get 70°
Next you can just (6(12)-2) or continuously substitute until you get the right answer.

1 4/7 as an improper fraction.
The mix fraction as an improper fraction is 11/7.
We have,
Mix fraction:
1(4/7)
This can be simplified as an improper fraction:
= {(7 x 1) + 4} / 7
= (7+ 4) / 7
= 11/7
Thus,
The mix fraction as an improper fraction is 11/7.

You randomly draw a marble from a bag, record is color, and then replace it. You draw a blue marble 11 out of 50 times. What is the experimental probability that the nes marble will be blue? Write your answer as a fraction, de mal, or percent. The experimental probabilty that the next marble will be blue is
Explanation:
This may seem like a trick question, but it's not. Your teacher simply wants to know how many times you got blue out of the number of times total. The numerator is the number of blue. The denominator is the number of total tries. The fraction 11/50 cannot be reduced because 11 and 50 share no common factors other than 1.
Notes:
11/50 = 0.22 = 22%The answer above applies to experimental probability only. The theoretical probability is likely different. We don't have enough info to compute the theoretical probability.find the value of x. round your answer to the nearest tenth.

the diagram shows a parallelogram. work out the value of x
Answer:
x = 39
Step-by-step explanation:
The opposite angles of a parallelogram are congruent, so
3x - 15 = 2x + 24 ( subtract 2x from both sides )
x - 15 = 24 ( add 15 to both sides )
x = 39
The value of x from the parallelogram is given by the equation x = 39°
What is a Parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
The four types are parallelograms, squares, rectangles, and rhombuses
Properties of Parallelogram
Opposite sides are parallel
Opposite sides are congruent
Opposite angles are congruent.
Same-Side interior angles (consecutive angles) are supplementary
Each diagonal of a parallelogram separates it into two congruent triangles
The diagonals of a parallelogram bisect each other
Given data ,
Let the parallelogram be represented as ABCD
Now , the total internal angle of a parallelogram is 360°
Now , the equation will be
∠A + ∠B + ∠C + ∠D = 360°
Substituting the values in the equation , we get
3x - 15 + 2x + 2x + 2x + 24 = 360° be equation (1)
On simplifying the equation , we get
9x + 9 = 360
Subtracting 9 on both sides of the equation , we get
9x = 351
Divide by 9 on both sides of the equation , we get
x = 39°
Therefore , the value of x is 39°
Hence , the equation is x = 39°

Answer:
Solution given:
perpendicular distance =height [p]=40m
base or horizontal distance [b]=198m
Hypotenuse or zip line [h]=?
Now
By using Pythagoras law
h²=p²+b²
h²=40²+198²
h=√40804
h=202m
So the Zip line is 202m long.
