Answer:
36cm
Step-by-step explanation:
Tan(14/12)=angle of ONP
Tan(42/X)=angle of LNM
singe those angels are the same;
Tan(14/12)=Tan(42/X)
14/12=42/X
14*X=42*12
X=(42*12)/14
X=36
pretty sure its 40cm
hope this helps :)
1 and 9/28
you need to put everything over the same denominator
21/28+16/28=37/28
this can be written as 1 9/28
6 is 100 times 0.06
0.06 times 100 = 6
67
Assuming you require to simplify the expression.
Using the rule of radicals
× ⇔
Simplifying the radicals
= = × = 6
= = × = 11
Then
2 + 5
= 2(6 ) + 5(11 )
= 12 + 55
= 67
