Which function is it?
i need to find the measure of angle L
Answer:
Angel L = 52°
Step-by-step explanation:
In ∆ JKL,
J = 8x + 6°
K = 2x + 2°
L = 4x+ 4°
L =?
Let's solve this question with the help of Angle Sum Property of a Triangle (ASPT).
We know that all angles in a triangle add up to 180°.
180 = ∆JKL
180 = J + K + L
180 = (8x + 6) + (2x + 2) + (4x + 4)
180 = 8x + 6 + 2x + 2 + 4x + 4
180 = 8x + 2x + 4x + 6 + 2 + 4
180 = 14x + 12
14x = 180 - 12
14x = 168
x = 168/14
x = 12°.
Now, L° = 4x + 4
= 4(12) + 4
= 48 + 4
= 52°.
solve by factorizing x² + 8x + 15 + 0

There are two right angled triangles
given that Tan A = Tan B
Find the value of X
Answer:
[tex]x = \frac{2}{3}[/tex]
Step-by-step explanation:
Given
See attachment for triangles
Required
Find x
First, calculate tan A
From the first triangle:
[tex]tan\ A= \frac{x + 2}{x}[/tex]
Next, calculate tan B
From the second triangle:
[tex]tan\ B= \frac{4}{3x-1}[/tex]
[tex]tan\ A = tan\ B[/tex]
So, we have:
[tex]\frac{x + 2}{x}= \frac{4}{3x-1}[/tex]
Cross Multiply
[tex](x + 2)(3x - 1) = 4 * x[/tex]
Open brackets
[tex]3x^2 + 6x - x - 2 = 4x[/tex]
[tex]3x^2 + 5x - 2 = 4x[/tex]
Collect Like Terms
[tex]3x^2 + 5x - 4x- 2 =0[/tex]
[tex]3x^2 + x- 2 =0[/tex]
Expand
[tex]3x^2 + 3x - 2x- 2 =0[/tex]
Factorize:
[tex]3x(x + 1) - 2(x+ 1) =0[/tex]
Factor out x + 1
[tex](3x - 2)(x +1) = 0[/tex]
Split:
[tex]3x - 2 = 0\ or\ x + 1 = 0[/tex]
[tex]x = \frac{2}{3}\ or\ x = -1[/tex]
x can not be negative, so:
[tex]x = \frac{2}{3}[/tex]

Answer: The weight = 33.75kg
Step-by-step explanation:
Given that
one cubic metre of ice weight is 80 kg
which is mathematically written as
1m³ of ice = 80 kg
Therefore 75 cm length of cubical block of ice =???
First
changing 75 cm to meters, we have 75/100 = 0.75 m
Volume of block = l³= 0.75³ = 0.421875m³
Given that
1m³ = 80kg
0.421875m³= 0.421875 x 80
= 33.75kg

Aviva deposited some amount of money at a 4% annual interest rate into her bank account. The money was left in the account for 18 months, and she did not make any more deposits.
If Aviva's money earned $240 interest after 18 months, how much money did she deposit into the account?
The amount of money that was deposited by Aviva into her bank account is $4,000.
Given the following data:
Interest rate = 4% = 0.04.Simple interest = $240.Time = 18 months.Conversion:
12 months = 1 year.
18 months = 1.5 year.
To determine the amount of money that was deposited by Aviva into her bank account:
How to calculate simple interest.Mathematically, simple interest is given by this formula:
[tex]I=PRT[/tex]
Where:
S.I is the simple interest.P is the principal or starting amount.R is the interest rate.T is the time measured in years.Substituting the given parameters into the formula, we have;
[tex]240=P \times 0.04 \times 1.5\\\\240=0.06P\\\\P=\frac{240}{0.06}[/tex]
P = $4,000.

If a =
-5i and b = -4x, then find the value of a+b in fully simplified form.
If a =-5i and b = -4x the value of a+b in the fully simplified form will be 5i-4x.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
It is given that,a =-5i and b = -4x
We have to find the value of a+b in a fully simplified form.
We have to apply the arithmetic operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
=a+b
= -5i-4x
Thus, if a =-5i and b = -4x the value of a+b in the fully simplified form will be 5i-4x.

What is the area of an EQUALATERAL triangle with a side length of 6? I'm getting 5.19615242, is this right?
Answer:
15.59.
Step-by-step explanation:
The altitude of equilateral triangle bisects the base
So 1/2 base = 3.
Altitude of the triangle is found from Pythagoras theorem:
= sqrt(6^2 - 3^2)
= sqrt27
Area = 1/2 base * altitude
= 3 * sqrt27
= 15.59

Find the value of x in the triangle shown below.
Answer:
58
Step-by-step explanation:
Since two of the sides are both 6.2, we know that this is an isosceles triangle. Thus, the two angles opposite of x are both equal (61 degrees).
The angles inside of a triangle always add up to 180, so now we have
180 = 61 + 61 + x
Solving for x, we get x = 180 - (61 + 61) = 180 - 122 = 58

A computer and printer cost a total of $900. The cost of the computer is three times the cost of the printer. Find the cost of each item.
The measure of A is 14 degrees greater than the measure of B. The two angles are complementary. Find the measure of each angle
Answer:
[tex]A = 52[/tex], [tex]B = 38[/tex]
Step-by-step explanation:
The sum of two complementary angles is always [tex]90[/tex]°
[tex]A + B = 90[/tex]
[tex]A = B + 14[/tex]
substitute [tex]A[/tex] for [tex]B = 14[/tex]
[tex](B + 14)+ B = 90[/tex]
[tex]2B + 14 = 90[/tex]
[tex]2B = 76[/tex]
[tex]B = 38[/tex]
input this into the original equation
[tex]A + 38 = 90[/tex]
[tex]A = 52[/tex]
