This is my work and only part 1
4x+7=35
4x=28
x=7
A corresponding solution of the matching equation is a fancier way of telling you to find the number that represents x
Answer:
-21
Step-by-step explanation:
3x7=21 and a negative x a positive is always negative
❥
So we can only find x if other two angles of triangle is given.
In angle B as u can see boxed shape angle is there then it probably means it's a 90° angle.
We know sum of angles of triangle = 180°
{Reson :-
There's a formula to fund sum of angles of figure
- (n-2) × 180
- (3 -2) × 180
- 1 × 180
- 180°
}
Now Let's proceed

Fill all the given values








Value of x = 35°
