The exact value of the y in the similar right triangle is 2.2360679775 units
<h3 /><h3>How to find the side of a triangle?</h3>
The triangles are similar.
Similar triangles have corresponding sides of equal ratio.
The corresponding angles of similar triangle are equal.
Therefore, using similar ratio,
y / 5 = 1 / y
cross multiply
y × y = 5 × 1
y² = 5
square root both sides
y = √5
Therefore,
y = 2.2360679775 units

Answer:
(a) = 60
(b) = 70
Step-by-step explanation:
(a) Sum of all the angles of a triangle is 180
This is an equilateral Triangle
which means all the sides are equal since all the sides are equal that means all the angles are equal

(b) this is an isosceles triangle with two equal sides that means the two opposite angles are equal

The formula

, for n=1 becomes

.
Comparing

with

, we see that
P=900, and 1+r=1.185, which means that r=0.185.
r=0.185 can be written as 18.5%, as a percentage.
Answer: 18.5%
