Answer: k = {8, -8}
<u>Step-by-step explanation:</u>
In order for a quadratic equation to have exactly one solution, the discriminant must equal zero. → b² - 4ac = 0
4x² + kx + 4 = 0
↓ ↓ ↓
a=4 b=k c=4
b² - 4ac = 0
k² - 4(4)(4) = 0
k² = 64
k = √64
k = ± 8
Given the two triangles, and the sine ratio formula is equal to:
Sin(x) = O/H
Where x is one angle of the triangle
O is the opposite side of the angle x
H is the hypotenuse of the triangle
To solve this we have to fine O/H = 4/5
So the answer is
Sin (P) = 16/20 = 4/5
<span>So angle P has the sine ratio of 4/5</span>

Factors of 30: 1,2,3,5,(6),10,15,30
Factors of 42: 1,2,3,(6),7,14,21,42
30 divided by 6, 42 divided by 6
(5) + (7)= 12
