Answer:
X = 40 degree
Step-by-step explanation:
First I would name the points whatever you do always name the points it really helps
So,
75 = a
50 = b
The middle point will be o
85 = c
X = d
Ok so,
Angle aob = y
Angle cod = z
Now,
75+50+y=180 (angle sum property)
y=180-125
y=55
Angle y = z (vertically opposite angles)
55+85+x=180 ( angle sum property )
x=180-140
Therefore x=40 degree
In higher classes you will be able to do this in your mind itself without calculation all you need is practice.
The answer is $37.86 !! hope this helps
Answer:
B.) 7 in
Step-by-step explanation:
A regular hexagon can be divided into 6 congruent equilateral triangle. The measure of an angle of an equilateral triangle is 60 deg. The angle formed by sides b and c measures 60 deg.
tan A = opp/adj
tan 60 deg = 12/b
b * tan 60 deg = 12
b = 12/(tan 60 deg)
b = 7 in
Answer:
infinite
Step-by-step explanation:
Let the linear equation in two variables be ax+by+c=0
Put values
Hence for any values it has infinite number of solutions .
including x=1 and y=3
