Answer:
y = 9√3
x = 18
Step-by-step explanation:
taking 30 as reference angle
b = y
p = 9
h = x
so
tan30 = p/b
1/√3 = 9/b
or, b = 9√3
so

Whats the choices?..............................................................................
Answer:
The terms are 9, 4, 3b and 7a.
The terms are 9 – 4 and 3b + 7a.
The terms are 9, -4, 3b, and 7a.
Step-by-step explanation:
Answer:
17 people
Step-by-step explanation:
135-50=85
85/5=17
Partial products are the products obtained during the intermediate stages in order to complete a multiplication process.
Consider 68
43, we have to determine the partial products in this.
Now, 
Expanding this, we get

= 
= 2400 + 180 + 320 + 24
= 2924
Hence,
and
are the required partial products in the product of 68 and 43.
So, Option 3 and 4 are the correct answers.
