Answer:
The value of an exterior angle is the sum of the two interior angles not adjacent to it so
a:
x = 64 + 45 = 
b:
3x + 6 = 153 so
3x = 147 so
x = 

Multiplying both sides of this equation by 3, to eliminate the fraction, we get:
9 + m = 6.
Next, we subtract 9 from both sides to isolate m: m = 6 - 9 = -3
Then m = -3.
Check: Subst. -3 for m in this equation:
9 - 3 6
------- = ------ = 2 (as expected). Thus, m = -3 is correct.
3 3
Problem #10:
4n - 9 = -9 Add 9 to both sides: 4n = -9 + 9 = 0.
Divide both sides by 4: n = 0.
Check: Substitute 0 for n: 4(0) - 9 = -9 is true.
Answer:

Step-by-step explanation:
just because
Answer:
74.8 m
Step-by-step explanation:
We are given that

Speed of peacock,v=10 km/h
Time,t=1 min 12 sec=60+12=72 s=
1 hour=3600 s
Distance=vt=
Using 1 km=1000 m
We know that

Using the formula


Hence, the peacock was at height of 74.8 m on the tree.
