Answer:
Let coefficient of linear and area expansion be α a n d β respectively. where ∆ T is change in temperature. For simplicity let us consider the case of square of side L. Therefore, coefficient of area expansion is twice the linear expansion.
In equiangular triangle ABC,
∠B = ∠C
∴ Side AB = AC
4x-10 = 5x-22
22-10 = 5x - 4x
12 = x
Therefore, the value of x = 12
Answer:
The perimeter of the triangle is 2+√2
Explanation:
Since one of the angles of the triangle is 90°, the triangle in question is a right angled triangle.
Since two angles of the triangle are also equal, then two of the its sides will be equal.
Let the opposite and the adjacent sides of the triangle be 1. To get the hypotenuse side, we will apply the Pythagoras theorem which States;
Hypotenuse² = Adjacent²+opposite²
Hyp² = 1²+1²
Hyp = √1²+1²
Hyp = √2
The third side of the triangle is √2.
The perimeter of the triangle will be the sum of all its sides i.e 1+1+√2
= 2+√2
The perimeter of the triangle will be 2+√2
Answer:
mostly because the desert is dry
Explanation:
and its not humid
Answer:
9
Explanation:
27=3y
Get y by itself, that is your main mission. In geometry, if you do one thing on one side, you have to do the same on the other. In this case:
27/3=3y/3
Cancel the 3<em>s</em> on the right side and solve the left.
9=y
