Answer:
57.5°
Step-by-step explanation:
For triangle ABC C = 90 Side AC = 13.5 Side BC = 8.6 Find the measure of angle B
We solve using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = Angle B
Opposite = Side AC 13.5
Adjacent = Side BC = 8.6
Hence:
tan θ = 13.5/8.6
θ = arc tan (13.5/8.6)
θ = 57.501354056°
Approximately = 57.5°
Therefore, Angle B = 57.5°
Answer: X- 4y - 12=0
step by step explanation:
First, move the constant to the left by adding its opposite to both sides
x-4y -12 = 12-12 =
X-4y-12 = 0
So the answer is X- 4y - 12=0
Answer:
10 + 7= 17
17 + 7= 24
24 + 7= 31
Step-by-step explanation:
Answer: r=14
Step-by-step explanation:
because they are vertical angles
7r+6=8r-8
solving for r you get
r=14
