The length of each congruent side of the isosceles triangle is given to be equal 2.75 inches while the base calculated to be equal to 23.5 inches
<h3>How to solve for the congruent sides</h3>
We first have to define x as the length of the congruent side. The question tells us that the base is 7 inches longer than 3x the length of 2 sides
This would be represented as:
= 3(2x) + 7
= 6x + 7
The perimeter of the shape is said to be 29, hence we would have
x + x + (6x + 7) = 29
= 2x + 6x + 7 = 29
= 8x = 29 - 7
8x = 22
x = 22 / 8
= 2.75
Given the value of x we would have to put it in
6x + 7
= 6 x 2.75 + 7
= 23.5
Therefore the length of each congruent side of the isosceles triangle is given to be equal 2.75 inches while the base calculated to be equal to 23.5 inches

So for variables, you just substitute the number in for the variable.
177 - 5r
If r = 9,
117 - 5 × 9
117 - 45
72
The arc is defined by an angle of 1.05 radians, and a length of 1.05 units.
<h3 /><h3>How to get the angle in radians?</h3>
Remember the relation:
180° = 3.14 radians.
Then:
60° = (60°/180°)*3.14 rad = 1.05 rad.
Now, for a circle of radius R, an arc defined by an angle θ has a length:
L = θ*R
Then the length of this arc is:
L = 1.05*1 unit = 1.05 units.
