X=40 degrees
100+2x=180
80=2x
x=40
Answer:
-14 and 4
Step-by-step explanation:
To find the values subtract 9 from -5, as well as add 9 to -5
-5-9= -14
-5+9= 4
I think it is 200 because if you cut it from the 2 points at the side you can solve the area for the 2 triangle and add the 2 areas
(Area of 1) + (Area of 2) = (Area of 3) this statement about the squares must be true.
What is Right angle traingle?
A right-angled triangle is a particular kind of triangle in which one of the angles is 90 degrees. The combined angles of the other two are 90 degrees. The triangle's base and perpendicular sides both include the right angle. The longest of the three sides, known as the hypotenuse, is the third side.
we know that;
By applying the Pythagorean Theorem;
.............................(1)
Area of the square says A1;
A1 = a^2 unit^2 ...............................(2)
Area of the square says A2;
A2 = b^2 unit^2 .................................(3)
Area of the square says A1;
A3 = c^2 unit^2 ..................................(4)
Replace the A1, A2, and A3 values in the equation 1 ;
A3 = A1 + A2
therefore;
(Area of 1) + (Area of 2) = (Area of 3).

Answer:
1)x=6
Step-by-step explanation:
step 1: add 2x to both sides.
x−15+2x=−2x+3+2x
3x−15=3
step 2: add 15 to both sides.
3x−15+15=3+15
3x=18
step 3: divide both sides by 3.
3x/3=18/3
x=6
answer:
x=6
good luck :)
hopefully, this helps
i don't really know what it is that you need but **please let me know if this was incorrcect**
have a nice day !!
