I got it wrong i need it help
Answers
Answer:
25
Step-by-step explanation:
Given,
Measurement of <1 = x + 10
Measurement of <2 = 4x + 5
Also, said in the question that both these angles are complementary.
Therefore, by the problem,
<1 + <2 = 90°
=> x + 10 + 4x + 5 = 90
=> x + 4x + 10 + 5 = 90
=> 5x + 15 = 90
=> 5x = 90 - 15 = 75
[tex] = > x = \frac{75}{5} [/tex]
=> x = 15
Now, we have got the value of x so,
Measurement of <1 is
<1 = x + 10 = 15 + 10 = 25 (Ans)

if cot a =5/12 then find the value of cosec A
Answers
Answer:
cosec A = 13/12
Step-by-step explanation:
Mathematically, we want to find the value of cosec A
sides 5,12 and 13 represent a Pythagorean triple. This means the last side of the right-triangle that contains 5 and 12 is 13
cot is the ratio of the adjacent to the opposite
Hence ; 5 represents the adjacent while 12 represents the opposite
cosec is the inverse of sine which is the hypotenuse to the opposite ratio
So, we have ;
cosec A = 13/12

The perimeter of a triangle is 27. Each side of the triangle has length 2x-3. What is the value of x?
Answers
Answer:
x=6
Step-by-step explanation:
To find the perimeter of the triangle you need to add up all the sides, so if all the sides are 2x-3 the equation will look like this;
2x-3+2x-3+2x-3=27
which when combining like terms will leave it to be;
6x-9=27
Than move all the factors besides x over to the right side;
6x-9+9=27+9
6x = 36
6x/6 = 36/6
x = 6
so your answer will be x=6
A box of chocolates contains milk chocolates and dark chocolates in the ratio 4:3
The box contains 35 chocolates
how many milk chocolates are there in the box?
Answers
Answer:
20 milk chocolates
Step-by-step explanation:
The first step is adding together 4 + 3. You will get 7. This is the total number of units in the box.
Then, divide 35 by 7. You will get 5 as the answer.
To find the number of milk chocolates, multiply 5 and 4. You will get 20 as the answer.
7x=35
x=5
milk chocolate 4(5) = 20
dark chocolate 3(5) = 15

y is inversely proportional to x.when y=7 x=9 a) work out an equation connecting y and x b) work out the value of y when x=21
Answers
Answer:
a) y = k/x
7 = k/9
b) y = 3
Step-by-step explanation:
From the question, we are told that:
y is inversely proportional to x.
Mathematically:
y ∝ 1/x
y = k × 1/x
y = k/x
k = Constant of Proportionality
a) work out an equation connecting y and x
To find this Equation,
y = k/x
when y=7 x=9
Hence:
7 = k/9
b) work out the value of y when x=21
We find the value of k first
7 = k/9
k = 7 × 9
k = 63
Hence, the value of y when x=21
y = k/x
k = 63, x = 21
y = 63/21
y = 3

The diagram shows two right-angled triangles. Calculate the value of x.
Answers
The value of x in the given diagram is 7cm.
What is tangent of an angle?The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
According to the given question.
We have a diagram in which we have two right angled triangles.
Now, in the upper right angled triangle
[tex]tan50 = \frac{0pposite side}{5}[/tex]
⇒ 1.19 = 0pposite side/ 5
⇒ opposite side = 1.19 × 5
⇒ opposite side = 1.2 × 5
⇒ opposite side = 6cm
Now, the opposite side w.r.t angle 50 degrees in the upper right angle triangle is a adjacent side w.r.t to angle 38 degrees in the lower right angle triangle.
So, in the lower right angle triangle.
[tex]tan38 = \frac{x}{adjacent side}[/tex]
⇒[tex]0.78 = \frac{x}{6}[/tex]
⇒ x = 0.78 × 6
⇒ x = 4.68
⇒ x = 7cm
Hence, the value of x in the given diagram is 7cm.
