Answer:
y - 7 = - (x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - and (a, b ) = (- 2, 7 ) , then
y - 7 = - (x - (- 2) ) , that is
y - 7 = - (x + 2)
Answer:
- Right Triangle-10.5 cm, 20.8 cm, 23.3 cm
- Not a Right Triangle-6 cm, 22.9 cm, 20.1 cm
Step-by-step explanation:
Given the sets of side lengths of a triangle:
- 10.5 cm, 20.8 cm, 23.3 cm
To verify whether each set of side lengths could be the sides of a right triangle, we use the Pythagorean Theorem. Note that the longest side is always taken as the hypotenuse.
- Pythagoras Theorem:
In the set of side lengths 10.5 cm, 20.8 cm, 23.3 cm
Clearly these satisfies the required theorem and thus are side lengths of a right triangle.
In the set of side lengths 6 cm, 22.9 cm, 20.1 cm
Clearly these does not satisfy the required theorem and thus are not side lengths of a right triangle.
Answer:
HL Theorem
Step-by-step explanation:
Here, we see that both triangles have a right angle, making them right triangles. We know that the hypotenuse must be equivalent, as it is the same line. Furthermore, we see that one of the legs from each triangle are equivalent. Therefore, we can use HL Theorem to prove these triangles are equal.
Answer:
5 * 10^10
Step-by-step explanation:
(9 * 10^10) - (4 * 10^10)
If the * 10^x are both the same then just take the numbers away.
