Tip - for finding the surface area of a triangle put two of them together so it forms a square find the area of that square and divide it by 2
4y=7x
The sum of the numbers is 22
so, x+y=22
x=(22-y)
by substitute (22-y) for x in the first equation.
Looking at the given diagram, angle AEC and angle DEB share the same vertex, E. They are described as vertically opposit angles. In geometry, vertically opposite angles are equal. This means that
Angle DEB = angl AEC = 50 degrees
The least amount of information needed to establish congruence is; Angles M and M' are congruent, and angles N and N' are congruent.
<h3>What is the least amount of information needed to determine if the two triangles are similar?</h3>
If follows from concept of congruence that two triangles are congruent only if all three angle measures are congruent or all corresponding sides are in the same ratio.
Hence, when angles M, N and M', N' are established as congruent, it follows that the measures are equal respectively.
Ultimately, the measure of angles L and L' are equal and hence, all three angles are congruent in each triangle.
Therefore, the least amount of information needed is; Angles M and M' are congruent, and angles N and N' are congruent.
