Answer:
∠A = 60° and ∠B = 30°
Step-by-step explanation:
Given in question as ,
Angle A is twice as large as its compliment angle B
Angles are compliment in nature when sum of these two angle = 90°
Now ∠A + ∠B = 90°
Again as per question ∠A = 2 times ∠B
So, 2 times ∠B + ∠ B = 90°
Or, 3 ∠B = 90°
So, ∠B =
Thus, ∠B = 30°
Now Put the value of angle B to get the value of angle A
So, ∠A = 90° - 30°
Or, ∠A = 60°
Hence ∠A = 60° and ∠B = 30° ANSWER
Answer: cos(54) because the cosine is = to the sine between two complementary angles and 36 + 54 = 90, which means they are complementary.

I think 42.46444 is the answer
Answer: y = - 9
Step-by-step explanation:
Two lines are said to be perpendicular if the product of their slope = 1 , that is , if the slope of the first line is and the slope of the second line is , then = , that is :
X = -1
The line given is ; 2x + y = - 4
Make y the subject of the formula so that the equation will be in slope - intercept form ; y = mx + c
that is
y = -2x - 4
comparing with the equation of line y = mx + c , it shows that = -2
Since the second line is perpendicular to this line , it means =
That is
=
Using the formula y - = m ( x - ) to find the equation of the line
= -8
= 2
substituting into the equation
y - (-8) = ( x - 2)
y + 8 = ( x- 2)
2(y+8) = x - 2
2y + 16 = x - 2
2y = x - 2 - 16
2y = x - 18
y = - 18/2
y = - 9
It’s A I think but I could be wrong
