Plz Help! I don't know how to solve this. The measures of two angles of a triangle are given. Find the measure of the third angle.
147° 12′, 30° 19′
51° 20′ 14″, 106° 10′ 12″

Example: Applying the Angle Sum of a Triangle Property
The measures of two of the angles of a triangle are 48° and 61°. See Figure 17.
Find the measure of the third angle, x.
SOLUTION 48° + 61° + x = 180° The sum of the angles is 180°.
109° + x = 180° Add.
x = 71° Subtract 109°.
The third angle of the triangle measures 71°.

Ummm I think the question is wrong, I don't fully understand.

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
