Example no. 1 <a and <c are corresponding angles
x + 70 = 3x
x - 3x = -70
-2x = -70
-2 -2
X = 35
m<a = x + 70
m <a = 35 + 70
m<a = 105​

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
