I assume that you want the measurement of angle A
A + (A + 38) = 90
angle A + (38 more than angle a) = are complementary
2A = 52
A = 26

Answer:
Option C: n = 32; p^ = 0.4
Step-by-step explanation:
The normal curve can be used in this case if; np ≥ 10 or n(1 - p) ≥ 10
A) For n = 28 and p = 0.3;
np = 28 × 0.3 = 8.4 < 10
Thus, it can't be used.
B) For n = 28 and p = 0.9;
np = 28 × 0.9 = 25.2 > 10 Ok
n(1 - p) = 28(1 - 0.9) = 2.8 Not Ok
Thus, it can't be used
C) For n = 32 and p = 0.4
np = 32 × 0.4 = 12.8 > 10 Ok
n(1 - p) = 32(1 - 0.4) = 19.2 > 10 Ok
Thus, it can be used
D) For n = 32 and p = 0.2
np = 32 × 0.2 = 6.4 < 10 Not Ok
Thus it can't be used.

The formula for the velocity, v is √2E/m
<h3>What is kinetic energy?</h3>
Kinetic energy is half the mass multiplied by the square of the speed of the object
It is written thus;
Kinetic energy = 1/ 2 × m × v²
To solve for 'v' mean that we should make 'v' the subject of formula
E = 1/ 2 mv²
E = 
cross multiply
To make 'v' the subject, we have
Thus, the formula for the velocity, v is √2E/m

Answer:
The last option: 3^(7/10).
Step-by-step explanation:
√3 * ⁵√3
= 3^1/2 * 3*1/5
= 3^(1/2*1/5)
= 3^(7/10).
