we can find the value of the x by hypotenuse formula,
as
1st biggest triangle we have its hypotenuse and side so we can find its base..if we got the base than we can find the value of x.
so,
c² = a² + b²
so,
c = 10
A = 7
so,
→10² = a² + 7²
→ 100 = a + 49
→ a = 100 - 49 = 51
→ a² = √51 = 7.14
and now let's find the value of x
so, after inserting values we got,
C = 7.14
b = 6
so,
c² = a² + b²
→ 7.14² = a² + 6²
→ 50.97 = a + 36
→ a = 50.97 - 36
→ a = 14.97
→ a² = √14.97 = 3.86
so value of x is 3.9 after rounding off
hope this answer helps you dear take care and may u have a great day ahead!
