The answer is 3, hope this helps!
Step-by-step explanation:
A.let n be 1
a1=2(1)+3
T1=5
let n be 2
2(2)+3
T2=7
T3=2(3)+3
=9
T4=2(4)+3
=11
Answer:
0, 1, 1.5, 1.8, 1.3
Step-by-step explanation:
Answer:
z = 24°
Step-by-step explanation:
The 3 angles 48, x and x form a straight angle and sum to 180°, thus
x + x + 48 = 180
2x + 48 = 180 ( subtract 48 from both sides )
2x = 132 ( divide both sides by 2 )
x = 66
The 3 angles in a triangle sum to 180°
sum the 2 known angles and subtract from 180
z = 180° - (66 + 90)° = 180° - 156° = 24°
1.2*3= 3.6
28-19=9
3.6*10^9
