Answer:
measure of angle 5 = 75 degrees
Step-by-step explanation:
given measure of angle 8 = 105 degrees,
angle 8 and angle 5 are in a linear pair so,
(the sum of angles in a linear pair is 180 degrees)
therefore, angle 8 + angle 5 = 180 degrees
therefore,. 105 + angle 5 = 180 degrees
angle 5 = 180 - 105
angle 5 = 75 degrees
Answer:
x = 29
Step-by-step explanation:
Given that both triangles are congruent to each other, therefore, their corresponding angles are congruent as well. This means all three angles in one is the same as all three corresponding angles of the other.
Therefore:
m<CAB = m<CDE = 74°
m<ABC = 2x (given)
m<BCA = 48° (given)
Thus:
m<CAB + m<ABC + m<BCA = 180° (sum of triangle)
Substitute
74 + 2x + 48 = 180
Add like terms
2x + 122 = 180
2x + 122 - 122 = 180 - 122
2x = 58
2x/2 = 58/2
x = 29
