Answer:
72°
Step-by-step explanation:
==>Given:
∆ABC
AB = Opposite side length = 9
AC = Adjacent side length = 3
==>Required:
The measure of angle B
==>Solution:
Since ∆ABC is a right angled triangle, and we are given two sides (opposite and adjacent sides), to find m<B, we'd use the trigonometry formula tan B = Opposite/Adjacent.
Thus,
tan B = 9/3
tan B = 3
B = tan^-1(3) = 71.5650512°
<B to the nearest degree ≈ 72°
Answer:
equation 'b': y = -3/4x + 5
equation 't': y = 4/3x - 2
Step-by-step explanation:
parallel lines must have the same slope
the slope of perpendicular lines must be opposite and reciprocal
10 7/12 - 9/12=(10/12+7/12)-9/12=17/12-9/12=8/12
127/12-9/12
Nope. Her solution doesn't seem reasonable. In order to subtract 9/12 from 10 7/12 you must convert 10 7/12 to an improper fraction. You should then have 127/12 where she has 10/12.
Hope this helps! =)
Answer:
They seem good to me but I think you should switch up the numbers ion know I gotta see
