2x/7 = 12/14
Multiply both sides of the equation by 7:
2x = 84/14
Simplify:
2x = 6
Divide both sides by 2 and your answer is....
x = 3
Answer:
The first question would likely be y=10.
The second question would likely be x=20.
This will be an obtuse angled triangle because one angle is greater than 90 degrees.
Answer:
x = 71
Step-by-step explanation:
Since 2 sides of the triangle are congruent then the triangle is isosceles.
Thus the 2 base angles are congruent
The sum of the 3 angles in the triangle = 180°, so
x = 
= 
= 71
It's difficult to spot what kind of help is needed.
There's no variable in that equation whose value needs to be found.
It appears to be simply a statement, saying that the tangent of 36 degrees
is (3 and 3/7) .
As such, it's false, since the tangent of 36 degrees is roughly 0.7265 .
What exactly is the question ?
