We can sort out this triangle as a
scalene triangle, that is, a triangle that has three unequal sides. It is also true that there are no equal angles for this type of triangles. If a scalene triangle has an angle of 90°, then this is called a right triangle. But this is not right triangle. Let's prove it:
We know that the Pythagorean Theorem establishes that:
Therefore, we can say that:
Accordingly:
<em>In fact, this is not a right triangle.</em>
I would solve this by using elimination, because you have opposite coefficients, (7x and -7x)<span />
Answer:
Step-by-step explanation:
Answer: The answer is 90.
Step-by-step explanation:
90+90= 180+90= 270
