Answer:
Both are right triangles. That means they both have a 90∘ angle. They also both have a 30∘ angle.
It follows that both triangles have a 60∘ angle:
180∘−90∘−30∘=60∘.
So they have three angles in common.
The triangles are CONGRUENT as per the AAA rule of congruency.
The equation of the line through those two points is . . . . . . . . . . X = -4 . / / / The line has no y-intercept and undefined slope. It's the vertical line that crosses the x-axis at -4 and goes up and down forever.
They are the same answer. .7 is in the 10th place which is the same as .70 just adding a zero doesn’t change the number
639÷9=71. You can check your answer by doing 71x9=639
