Equilateral triangle<span> is a </span>triangle<span> in which all three sides are equal
</span>also 3 angles are equal and each angle = 60 degrees
so
2x - 4 = 60
2x = 64
x = 32
hope it helps
B would be the correct answer
<h3>
7.</h3><h3>
The required equation of the line is y= 2x-5</h3><h3>
8.</h3><h3>
y=30</h3>
Step-by-step explanation:
Given , a line passes through the points (1,-3) and (3,1)
The equation of line which passes through the points and is
Here and
The required equation of the line is
8.
Given, y varies directly with x and y=24 when x=8
Therefore,
.........(1)
y = 24 when x=8
Equation (1) becomes
y= 3x
So, when x=10
y=3×10
⇒y=30
Then he is travelling 24 miles per hour
Answers:
(x+2) = 55 degrees
x = 53 degrees
the given is 72 degrees
Explanation:
A triangle always equals 180 degrees. It was given that one of the angle measures is 72 degrees. 180-72=108. Now I need to find the value of x. (x+2)+x=108. Solving this equation I get x=53. Substitute this back into the angle measures and u get the answers as stated above.
