Answer: evaluate it is 52
Step-by-step explanation:
All the angles of a triangle add up to 180 degrees.
30+39+<4= 180
69+<4= 180
Subtract 69 on both sides.
<4= 111 degrees
<1 and <4 are supplementary and adjacent. They equal 180 degrees as well.
111+<1= 180
<1= 69 degrees
I hope this helps!

Answer: magnitude of an earthquake with an energy release of 7.079 X 10^26 =8
Step-by-step explanation:
Given that the magnitude M of an earthquake can be expressed by the equation
M=(2/3)log E - 9.9
Given that Energy release , E=7.079 X 10^26
Magnotude , M=(2/3)log E - 9.9
=2/3 log7.079 X 10^26 -9.9
2/3 x 2.8499719 -9.9
17.8999813 -9.9
=7.9999
rounded to 8 magnitude
