Answer:
m∡A = 50°
Step-by-step explanation:
since they are complementary they must equal 90°
4x+6 + 4x-4 = 90
8x + 2 = 90
8x = 88
x = 11
∡A = 4(11)+6 = 44+6 = 50
Answer:
B
Step-by-step explanation:
5x+2+33=90
5x=90-35=55
x=55/5=11
X=379.2/n
N=379.2/x
I hope that helps
To find Angle A we use cosine
cos ∅ = adjacent / hypotenuse
From the question
The adjacent is 17
The hypotenuse is 38
So we have
cos A = 17/38
A = cos-¹ 17/38
A = 63.4
<h3>A = 63° to the nearest degree</h3>
To find Angle C we use sine
sin ∅ = opposite / hypotenuse
From the question
The opposite is 17
The hypotenuse is 38
So we have
sin C = 17/38
C = sin-¹ 17/38
C = 26.57
<h3>C = 27° to the nearest degree</h3>
Hope this helps you
Answer:
2x - 4
Step-by-step explanation:
2(3x + 6) = 6x + 12
2(-2x - 8) = -4x -16
6x + 12 - 4x - 16 = 2x - 4
