The sum of all the angles in a triangle is equal to 180°
Since the given triangle is an isosceles ∆ therefore the angles opposite to the equal sides with also be the same.
now from the diagram: 90° + 2x° = 180°
Therefore x = 45

Given that a = 3 and b = -1, what is the value of 2a - b?
Answers
Answer:
the answer is 7.
Step-by-step explanation:
here's why......if u place the 3 where a is it will become multiplication so that would be 2 times 3 minus b now but if u place -1 the minus becomes addition so it will be 6+1 which is 7.
Answer:
The value of expression when a=3 and b=-1 is 7
Step-by-step explanation:
Given expression is:
2a - b
Also given that
a = 3
b = -1
In order to find the value of the expression, we have to put 3 in place of a and -1 in place of b in the expression
So putting the values
[tex]=2(3)-(-1)\\=6+1\\=7[/tex]
Hence,
The value of expression when a=3 and b=-1 is 7

Answer:
N165.53°E
Step-by-step explanation:
Given the following vector points
Vx = -43.0units
Vy = 11.1 units
The direction of the vector is expressed using the formula:
θ = tan^-1(Vy/Vx)
θ = tan^-1(11.1/-43.0)
θ = tan^-1(0.2581)
θ = -14.47°
Since tan is negative in the second quadrant, hence the required direction will be θ = 180-14.47
θ = 165.53°
Hence the direction is N165.53°E

A company makes spherical tanks that store chemicals. Their standard model has a diameter of 6 meters, but a customer needs a larger tank whose capacity is 2.5 times the volume of the standard model. What is the approximate diameter of this larger tank? Round to the nearest tenth.
Answers
Answer:
The approximate diameter of the larger tank is 8.10 meters
Step-by-step explanation:
Here, we want to calculate the diameter of the larger tank
The volume of a sphere
V = 4/3 * π * r^3
Let us calculate the volume of the standard model
That will be;
Since diameter is 6 and r = d/2
r = 6/2 = 3 meters
V = 4/3 * π * 3^3 = 36 π m^3
Now, the volume of the larger tank is 2.5 times of this;
The volume of the larger tank is 2.5 * 36 π = 90 π m^3
So we can calculate the radius of this before we calculate its diameter
4/3 * π * r^3 = 90 π
4r^3/3 = 90
r^3 = 270/4
r^3 = 67.5
r = 3x√(67.5)
r = 4.07 m
Diameter here is 2 times this
= 4.07 * 2 = 8.14

A 20-dirham note is 13 cm long. How many such notes need to be placed one after the other without overlapping to cover a length of 1 1 2 m?
Answers
Answer:
861 (approx)
Step-by-step explanation:
It is given that there is a note of 20 dirham. The 20 dirham note is 13 cm long. And we have to place the 20 dirham notes to cover a length of 112 m without overlapping the notes.
We know that :
100 cm = 1 m
∴ 13 cm = 0.13 m
In order to cover a length of 112 m, we have to divide 112 by 0.13, i.e.
[tex]$=\frac{112}{0.13}$[/tex]
[tex]$=\frac{11200}{13}$[/tex]
= 861 (approx)
