Step-by-step explanation:
I am not sure if I understand you right about what is needed.
I would understand we need the angle BAC (at A).
first of all, this is a right-angled triangle.
Pythagoras applies :
c² = a² + b²
with c being the Hypotenuse (side opposite of the 90° angle).
in our case that means
AC² = x² + y² = 4² + 6² = 16 + 36 = 52
AC = sqrt(52)
now we can use the law of sine to get the other angles.
a/sin(A) = b/sin(B) = c/sin(C)
with the sides and the corresponding angles being opposite.
in our case
y/sin(A) = AC/sin(B) = AC/sin(90) = AC
sin(A) = y/AC = 6/sqrt(52) = 0.832050294...
the angle A = 56.30993247...° ≈ 56.3°

23 - 2x = 10 ??!! HELP PLSS
Answers
x = 6.5
Explanation:
[tex]\sf 23 - 2x = 10[/tex]
subtract 23 from both sides
[tex]\rightarrow \sf 23-2x-23=10-23[/tex]
simplify the following
[tex]\rightarrow \sf -2x=-13[/tex]
divide both sides by -2
[tex]\rightarrow \sf \dfrac{-2x}{-2}=\dfrac{-13}{-2}[/tex]
simplify
[tex]\rightarrow \sf x=\dfrac{13}{2}[/tex]
in decimals
[tex]\sf \rightarrow x = 6.5[/tex]
Recheck the following
[tex]\hookrightarrow \mathrm{23 - 2(6.5) = 10}[/tex]
[tex]\hookrightarrow \mathrm{23 -13 = 10}[/tex]
[tex]\hookrightarrow \mathrm{10 = 10}[/tex]
L.H.S = R.H.S thus. x = 6.5

a)use the letter x for the uknown number
b) solve the equation
Answers
Answer:
x = 6
Step-by-step explanation:
i think of a number multiply it by 3 and add 4 i get 22.
x = a number
x is being multiplied by 3 (3*x or 3x), thening add 4 is equal to 22.
3x + 4 = 22
- 4 - 4
3x = 18
/3 /3
x = 6
Therefore, the unknown number is 6.

The point that is marked on the number line is - 0.875.
How to read a number line?According to the number line diagram, the right side after zero is the positive side while the left side before zero is the negative side.
The marked point is before zero, therefore, the marked point on the number line is surely a negative number.
Each step in the number line represents a step of 0.125.
Hence, the marked point represents 7 steps from zero, therefore, the marked point is -0.875.
