Answer:
a. 40°
b. 21°
Step-by-step explanation:
a. Reference angle = θ
Opposite = 5
Adjacent = 6
Apply TOA:



(nearest degree)
b. Reference angle = x
Opposite = 5
Hypotenuse = 14
Apply SOH:



(nearest degree)
Part A: The answer is B.
As vertically opposite angles are equal
x+10=4x-35
10=3x-35
45=3x
x=15
Part B: The answer is D.
We'll substitute in the value of X in one equation.
x+10
=15+10
=25
As the two angles are equal bot must be 25 degrees.
Answer:
The coordinates of point B are (6,7).
Step-by-step explanation:
Given points are
Blue = A(-4,8)
Purple = M(1,7.5)
Green = B
It is given that point M is the midpoint of point A and B.
Let coordinates of points are (a,b).
Midpoint of two points is


Coordinates of midpoint are (1,7.5).

On comparing both sides we get


Therefore, the coordinates of point B are (6,7).
Answer:
B: 12
Step-by-step explanation:
length of one side =150
length of one path =12.5
Number of patches= 150 / 12.5
Number of patches = 12
