The value of the variable 'x' is 30°. Then the measure of the angle ∠C will be 60°.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
A triangle labeled A B C. Side BC is the base, side AB is perpendicular, and side AC is the hypotenuse. Angle A is labeled x degrees, angle B is labeled 3x degrees, and angle C is labeled 2x degrees.
Then the equation is given as,
x + 2x + 3x = 180°
6x = 180°
x = 30°
Then the measure of the angle ∠C is calculated as,
∠C = 2 × 30°
∠C = 60°
The value of the variable 'x' is 30°. Then the measure of the angle ∠C will be 60°.

(3m+13)+(4m+21) simplified
Answer:
(7m+34)
Step-by-step explanation:
Add like terms 3m+4m=7m, 13+21=34
You have to make sure to add like terms. In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

Is f(x)=6x a direct variation
Answer:
[tex]f(x)=6x[/tex] is a direct variation.
Step-by-step explanation:
Given the function
[tex]f(x)=6x[/tex]
We have to determine whether the equation [tex]y=6x[/tex] is a direct variation or not.
As we know that in direction variation, y and x increase or decrease by the same factor by the formula
[tex]y=kx[/tex]
where 'k' is the constant of variation
Given the function
[tex]y=6x[/tex]
Here 6 is the constant of variation ∵ [tex]y=kx[/tex]
Also y and x increase and decrease by the same factor
For example,
when x=6, y = 6(x)=6(6)=36
when x=8, y = 6(x) = 6(8) = 48
Hence, when x increase, the y increases by the same factor.
Therefore, [tex]f(x)=6x[/tex] is a direct variation.

following square pyramid:
4 cm
6 cm
SA = [?] cm^2
Answer:
Lateral surface area= 48cm^2
Step-by-step explanation:
for anyone who needs the lateral surface area.
The total surface area of the square pyramid with a base side length of 6 cm and a slant height of 4 cm is 84 square centimeters.
We have,
Base side length (s) = 6 cm
Slant height (l) = 4 cm
Area of square = s²
Area of base = 6² = 36 cm²
A square pyramid has four triangular lateral faces with equal area.
The formula for the area of a triangle.
Area of triangle = 1/2 * base * height
Area of lateral surface of the triangle = 1/2 * 6 cm * 4 cm = 12 cm²
Total lateral area = 4 * 12 cm² = 48 cm²
Total surface area = Area of base + Total lateral area
Total surface area = 36 cm² + 48 cm²
Total surface area = 84 cm²
Therefore,
The total surface area of the square pyramid with a base side length of 6 cm and a slant height of 4 cm is 84 square centimeters.

Make r the subject of the formula t=r/r-3
Answer:
[tex]r = \frac{3t}{t-1}[/tex]
Step-by-step explanation:
[tex]t = \frac{r}{r - 3}[/tex]
Cross multiply,
t(r - 3) = r
tr - 3t = r
tr = r + 3t
tr - r = 3t
r(t -1) = 3t
[tex]r = \frac{3t}{t-1}[/tex]
Answer:
r = 3t/(t - 1)
Step-by-step explanation:
t = r/(r - 3)
t(r - 3) = r
tr - 3t = r
tr = r + 3t
tr - r = 3t
r(t - 1) = 3t
r = 3t/(t - 1)
