Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
5x + 7 + 4x + 2 + 90 = 180 , that is
9x + 99 = 180 ( subtract 99 from both sides )
9x = 81 ( divide both sides by 9 )
x = 9
Then
∠ ACB = 4x + 2 = 4(9) + 2 = 36 + 2 = 38°
∠ BAC = 5x + 7 = 5(9) + 7 = 45 + 7 = 52°
-----------------------------------------------------------------------
Since the triangles are congruent then corresponding angles are congruent , so
∠ B = ∠ E
6x + 10 = 70 ( subtract 10 from both sides )
6x = 60 ( divide both sides by 6 )
x = 10
Answer:
B
Step-by-step explanation:
We need the picture or is it just the question?
Answer:
mode which is c
Step-by-step explanation:
Answer:
Step-by-step explanation:
Isolate the term of x from one side of the equation.
<h3>x-5≤10</h3>
<u>First, add by 5 from both sides.</u>

<u>Solve.</u>
<u>Add the numbers from left to right.</u>


- <u>Therefore, the solution is x≤15, which is our answer.</u>
