Answer: C
Exp:
∠DXC = 90°
∠CXB = 90°
supplementary = 180°
90+90= 180
Answer:
The degrees of angle x is 180 degrees.
Step-by-step explanation:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of x.
Answer:A
Step-by-step explanation:
A is the correct answer
Hypotenus=h=13
Adjacent=a=5
Opposite=o=12
We can test by Pythagoras rule if it obey
h^2=o^2+a^2
13^2=12^2+5^2
13x13=12x12+5x5
169=144+25
169=169 it obeyed
