Answer:
7) m = 6
8) k = 15
9) a = -12
10) x = 1
11) n = 4
12) r = 11
Step-by-step explanation:
<h3><u>Solution</u> : </h3>
Solving all the questions step by step!
7) 1 = 6+m/12
- Hence, the value of m is 6.
8) 8 = 3 + k/3
- Hence, the value of k is 15.
9) -4(-8+a) = 80
- Hence, the value of a is -12.
10) 8(x-1) = 0
- Hence, the value of x is 1.
11) n/2 - 1 = 1
- Hence, the value of n is 4.
12) 1 = r-3/8
- Hence, the value of r is 11.

Answer:
1e+15
Step-by-step explanation:
2/4 is greater that 2/6 because ur splitting 2 only by 4, and splitting by 6 would obviously be less
Answer:
x = 8.8
Step-by-step explanation:
take 20 degree as reference angle .the,
hypotenuse = OQ = x (hypotenuse is always opposite of 90 degree)
perpendicular(opposite) = PQ 3 (opposite of reference angle is perpendicular or also called as opposite)
base(adjacent) = OP (side which lies on the same line where 90 degree and reference angle)
using sin rule
sin 20 = opposite / hypotenuse
0.34 = 3 / x
x = 3/0.34
x = 8.82
x = 8.8
