Answer:
x=65
Step-by-step explanation:
triangle with angle a is isosceles triangle
this means that the other 2 angles within the triangle on the left (triangle with angle a) are the same.
so if a=44
the other two angles would equal
= 68
the angle on the right of angle a, is opposite angles with the left corner of the traingle with angle x.
rule: opposite angles are equal
thus, that angle is also equal to 68
for the triangle with angle b, it is also an isosceles
if B = 47
then the other angle is also 47, we can ignore the tip of the triangle because we do not need it to find x.
since b is opposite angles with the right corner of triangle with angle x then
that angle also equals 47
now we know two angles of the triangle with angle x
thus to find x
180-47-68 = 65

<h3>What are algebraic expressions?</h3>
Algebraic expressions are seen as expressions that consist of factors, variables, terms, coefficients, and certain constants.
These expressions are also known to be composed of some arithmetic operations, which includes;
- Subtraction
- Addition
- Division
- Multiplication
- Parentheses
- Bracket, etc
Given the expression;
(2x-4)^2=16
√(2x-4)^2 = 16
Find the square root of the expression, we have;
√(2x -4)^2= √16
Find the values
2x - 4 = 4
collect like terms
2x = 4 + 4
Add like terms
2x = 8
Make 'x' the subject of formula
x = 8/2
x = 4
Hence, the value is 4

Answer:
x = -3
Step-by-step explanation:
You will have to distribute first
7 -2x -11 + 9 -3x = 20
Then, combine you like terms
-2x -3x = -5x
7 -11 +9 =5
Then you write it as an equation
-5x +5 = 20
Next you will want to have x by itself which means you have to get rid of the 5 by substracting 5 on each side (opposite of addition is substraction)
-5x = 15
Then you divide each side by -5 ( opposite of multiplication is division)
x= -3
Hope this helped :D
