Answer:
60
Step-by-step explanation:
x = (1/2)(172 - 52)
x = (1/2)(120)
x = 60
Answer:
137°
Step-by-step explanation:
If we know that a set of angles form one of these special relationships, we can determine the measure of the other angle. To determine the supplement, subtract the given angle from 180. 180 - 43 = 137° The supplement of 43° is 137°.
The LCD of 11/20 and 31/45 is 180
20 40 60 80 100 120 140 160 180
45 90 135 180
Answer:
3^(k+2) = 9m/ 26
Step-by-step explanation:
Let 3^k = y :
y×3^3-y = m
26y = m
26×3^k = m
3^(k+2) = m/26×3^2
Therefore 3^(k+2) = 9m/26
