Answer: The ΔVZX and ΔWXZ are not congruent by SAS.
Explanation:
It is given that the VX = WZ = 40 cm and ∠ZVX = ∠XWZ = 22°.
Draw a figure as shown below,
According to the SAS rule of congruence, two triangles are congruent if two sides and their inclined angle is equal.
From the given figure it is easily noticed that in ΔVZX and ΔWXZ,
(given)
(given)
(common side)
Since we have two sides and one angle is same. but we can not conclude that the ΔVZX and ΔWXZ are congruent by SAS, because the given angle is not the inclined angle of both equal sides.
Therefore, the ΔVZX and ΔWXZ are not congruent by SAS.
An isosceles triangle is a special type of triangle that has two equal sides. Consequently, the two base angles are also equal. Since the interior angles of a triangle should sum up to 180°, the general equation should be
180° = 2*Base angle + Vertex angle
Let the base angle be x. Thus, the vertex angle is equal to
Vertex angle = 4x - 6
Substituting,
180 = 2x + 4x - 6
x = 31°
Vertex angle = 4(31°) - 6
Vertex angle = 118°
1.Design a number line containing five (5) points
For this case what you should do is place a line with five points.
You can think of one of the axes of the Cartesian plane, for example, the x-axis. We place five separate points in that line the same distance.
line: 0 1 2 3 4 5
a. Round off the total population to the nearest hundred thousand people
nearest hundred thousand means
100,000
Then rounding off we have:
10,160,555
hundred thousand: 10,161,000
b. Round off Benin's area in square miles to the nearest thousand.
nearest thousand means
1,000
Then rounding off we have:
43,475
thousand: 44,000
Round off the number of miles of surfaced roads to the nearest ten. nearest ten means
10
Then rounding off we have:
870
ten: 870
d. Round off the number of people who live in rural areas to the nearest million
nearest million means
1,000,000
Then rounding off we have:
3,657,790
million: 4,000,000
