Answer:
AC=9 cm
ABC is not a right angled triangle
Step-by-step explanation:
AB=8cm
BC=5cm
22=AB+BC+AC
AC=22-8-5
AC=9
since AC is the longest,
using Pythagoras theorem
AC^2=BC^2+AB^2
9^2=8^2+5^2
81=64+25
81=89
therefore, it is not a right angled triangle
No it is not a right triangle.
Use the Pythagorean theorem to answer this question
1. find the missing side
8+5+x=22
13+x=22
x=9
2. Plug what you know into the Pythagorean theorem
a^2 +b^2=c^2
8^2+5^2=9^2
(if this is true then it is a right angle)
64+25=81
89≠81
You would need 6 1/4 cups of sugar.
675
1.55
3750+900 = 4650
4650/3000 = 1.55
The required value of y is 4800
i can only say that you should use this forumla, the sins law
sin(a)/A = sin(b)/B = sin(c)/C
