Answer:
15
Step-by-step explanation:
5:22=15:66, simply multiply 3 in the right hand side
B. 8+(-10)
Explanation:
8-10 is -2
If you try all the answers, 8+-10=-2
1) 110+30+a = 180
a = 180-140 = 40
Obtuse angled triangle
2) 50+50+C = 180
C=180-100 =80
Acute angled triangle
3) 45+45+b =180
b =180-90 = 90
Right angled triangle
4) 45+60+C = 180
C = 180-105 =75
Acute angled triangle
5) 94+47+b =180
b = 180-141=39
Obtuse angled triangle
6)81+53+a = 180
a =180-134 = 46
Acute angled triangle
7) 38+45+b =180
b = 180-83 =97
Obtuse angled triangle
8) 36+54+C =180
C =180-90 = 90
Right angled triangle.
Answer:
Number one is Linear, Number two is Exponential, and Number three is quadratic
Step-by-step explanation:
Answer:
you divide 15 by 2 to get the radius, then do pie times radius to the second power, so
3.14*7.5*7.5= 23.55
that is ur answer!
