Isocoleese means 2 angles are same, normally the base angles
so since it says they measure 42
rememeber that all angles in traingle add to 180
so base angles+vertex angle=180
base angles aer both 42 so 
2 times 42+vertex angle=180
42 times 2=84
so
if veretx angle=z then
84+z=180 
answer is B

Answer:
78
Step-by-step explanation:
Given that:
First day (a) = 1
1 more pebble every subsequent day than the previous day
Tn = a + (n - 1)d
d = common difference ; difference between pebbles in two successive days = 1
n = nth day
At the end of the 12th day;
Tn = a + (n - 1)d
T(12) = 1 + (12 - 1) 1
T(12) = 1 + 11
T(12) = 12
Appling the sun if arithmetic progression formula : Sum of AP:
n/2 (a + Tn) 
n = number of terms
12/2 (1 + 12)
6(13)
= 78
 
        
             
        
        
        
Answer:
m = 3.625
Step-by-step explanation:
1.2m + 0.65 = 5
~Subtract 0.65 to both sides
1.2m = 4.35
~Divide 1.2 to both sides
m = 3.625
Best of Luck!
