Answer:
4.6
Step-by-step explanation:
Use sine rule to find the number that belongs to the box.
Thus:
a = ?? (the number in the green box)
b = 5
A = 38°
B = 42°
Plug in the values
Multiply both sides by sin(38)
(nearest tenth)
Answer:
14^2/15
Step-by-step explanation:
70/15 simplifies to 14/3
14/3 X 14/5
= 14^2/15
Answer: 10
2AX=BD
2(3y-5)=5y
6y-10=5y
add 10 to each side 6y+10-10=5y+10
6y=5y+10
subtract 5y from each side 6y-5y=5y-5y+10
6y-5y=y
y=10
10cm, 9cm, 9cm
To make a triangle 2 of the sides must be the same length
