Answer:
X=64°
Step-by-step explanation:
Solution,
x+54°=118° because the sum of two interior angles is equal to the opposite non adjacent exterior angle.
x+54°-54°=118°-54°
x=64°
Answer:
64 degrees
The Process:
54 is already a number that's not going to change, so that's fine. 118 is an outside angle, and a flat line is 180 degrees, so to find the inside angle, you have to do 180 - 118. Once again, there are 180 degrees in a triangle to you need to add 180 - ((180 - 118) +54) and you have the value of x.

The sum of three numbers is 62. The second number is triple the first, and the third is six more than the
second. Find the numbers.
Answers
Answer:
The numbers are 8, 24 and 30
Step-by-step explanation:
Let x be the first number.
If the second number is triple the first, then the second number is 3x
If the third number is the second number plus six, then the third number is 3x + 6
So therefore the equation is:
[tex]x + 3x + (3x + 6) = 62[/tex]
Solving for x,
[tex]x + 3x + 3x + 6 = 62\\7x = -6 + 62\\7x = 56\\x = 8[/tex]
But why is the second number 24?
[tex]3x = 24\\3(8) = 24\\24 = 24[/tex]
And why is the third number 30?
[tex]3x + 6 = 30\\24 + 6 = 30\\30 = 30[/tex]

How Does 2 / 0.1 become 20?
Answers
The decimal value 0.1 converts to the fraction 1/10
This is because the 1 in 0.1 represents "one tenth", as its in the tenths place.
So this means 2/0.1 is the same as 2/(1/10) or [tex]2 \div \frac{1}{10}[/tex]
Then we can follow these steps:
[tex]2 \div \frac{1}{10} = \frac{2}{1} \div \frac{1}{10}\\\\\\2 \div \frac{1}{10} = \frac{2}{1} \times \frac{10}{1}\\\\\\2 \div \frac{1}{10} = \frac{2*10}{1*1}\\\\\\2 \div \frac{1}{10} = \frac{20}{1}\\\\\\2 \div \frac{1}{10} = 20\\\\\\[/tex]
Note in the second step, we flip the second fraction to go from a division problem to a multiplication problem. The general rule is [tex]\frac{A}{B} \div \frac{C}{D} = \frac{A}{B} \times \frac{D}{C}[/tex]. The first fraction does not flip.

simplify -2(x-4)-8(6-8x)
Answers
The simplified form of the expression is 2(31x-20).
Given the expression is -2(x-4)-8(6-8x).
Expressions in mathematics are mathematical statements containing at least two terms containing numbers or variables or both connected by an intermediate operator.
The given expression is solved by using the distributive property a(b+c)=ab+bc, we get
-2(x-4)-8(6-8x)=-2x-4(-2)-8(6)-8(-8x)
-2(x-4)-8(6-8x)=-2x+8-48+64x
Now, we will simplify the above expression by adding or subtracting like terms, we get
-2(x-4)-8(6-8x)=62x-40
-2(x-4)-8(6-8x)=2(31x-20)
Hence, the simplified form of the given expression -2(x-4)-8(6-8x) is 2(31x-20).

Answer:
B (Base surface area) = 16 [tex]m^{2}[/tex]
P (Perimeter of the base) = 16 m
H (Height) = 6 m
L (Not sure what L means. I assume it's the slant height??) = 6.32 m
LA (I assume lateral surface area) = [tex]50.59 m^{2}[/tex]
SA (I assume total surface area) = [tex]66.59 m^{2}[/tex]
V (volume) = [tex]32 m^{3}[/tex]
Step-by-step explanation:
Sorry if anything is wrong. It would be more helpful to put the names, instead of acronyms.
Perimeter of base=4(4)=16m
Area of base=4²=16m²
Height=6m
Slant height=6.3m
Lateral surface area=4(1/2(4)(6.3))=8(6.3)=50.54m²
Total surface area=50.54+16=66.54m²
Volume=a²h/3=4²/(6)/3=16(2)=32m³
