Answer:
Step-by-step explanation:
We are given two congruent sides.
The third side AB is common and therefore congruent to itself.
It gives us 3 congruent sides.
This is a side-side-side or SSS postulate.
Correct choice is B
Answer:
O = (3,3)
Explanation:
The <em>altitude</em> of a triangle is the perpendicular from a vertex to the opposite side.
The orthocentre (O) of a triangle is the point where the three vertices intersect.
We must find the equations for only two of the altitudes, because the third will also intersect at that point.
===============
Your three points make a right triangle.
The altitude of B is side AC.
The altitude of C is sde AB.
Their point of intersection at A (3,3) is the orthocentre of thetriangle.
Answer:
19
Step-by-step explanation:
19 * 2 is 38.
38 -7 = 31
Answer:
No solutions.
Step-by-step explanation:
y = 5/2x + 2
2y = 5x + 8
Plug the first equation into the second.
2(5/2x + 2) = 5x +8
5x + 4 = 5x + 8
5x + 4 cannot equal 5x + 8, so this system of equations has no solutions.
Step 1. Take out the constants
(4 * 7)xx^2
Step 2. Simplify 4 * 7 to 28
28xx^2
Step 3. Use the Product Rule
28x^1 + 2
Step 4. Simplify 1 + 2 to 3
28x^3
