Yes it is equivalent.Good luck
Answer:
A. 41°
Step-by-step explanation:
The triangle is isosceles, so A is congruent to C, which is the complement of ∠DBC.
... ∠A = 90° -49° = 41°
Answer:
4)x=15
5)137 degrees
6)supplementary
7)complentary
8)neither
Step-by-step explanation:
4) complementary angles sum = 90
so (3*15+30)
45+30=75
angle 1+angle 2=90
angle 1+75=90
90-75=15
angle1=15
5) angle z is a linear angle which means angle43+anglez=180
180-43=137 degrees
6) supplementary angles =180 degrees
53+127=180
so these angles are supplementary
7) complementary angles =90
56+34=90
so these angles are complementary
8) angles are vertical
HOpe this helps plz vote my answer the brainiest if it does!!!
