Answer:
C
Step-by-step explanation:
Hey There!
So if you didn't know in an isosceles trapezoid the non parallel sides are congruent
So given the base lengths and the perimeter we subtract the given length from the perimeter and divide that by 2
40-10=40
30-14=16
16/2=8
so the lengths of the non parallel sides would be 8 cm and 8 cm

Answer:
From given relation the value of β is 37.5°
Step-by-step explanation:
Given as :
α and β are two acute angles of right triangle
Acute angle have measure less than 90°
Now given as :
=
Or, =
SO, =
Or, 90° = +
or, 90° = + 4x
Or, 90° =
So, x = = 15°
∴ =
So, = sin
∴ The value of Ф_1 = = 37.5°
Similarly =
So ,The value of Ф_2 = = 52.5°
∵ β α
So, As 37.5°52.5°
∴ β = 37.5°
Hence From given relation the value of β is 37.5° Answer
