The picture has a quadrilateral with ABCD angles.
∠A=90° is right angle
∠B=105° is obtuse angle
∠C=75° is acute angle
∠D=90° is right angle
Given that,
The picture has a quadrilateral with ABCD angles.
The angle are
∠A=90°
∠B=105°
∠C=75°
∠D=90°
We have to clarify the angles of the quadrilateral.
∠A is right angle because the right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection.
∠B is obtuse angle because a form of angle known as an obtuse angle is one that is always greater than 90° but less than 180°.
∠C is acute angle because an acute angle is one that is smaller than 90 degrees in length. L-shape shapes at 90°
∠D is right angle because the right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection.

Answer:
i8765
Step-by-step explanation:
Before:
The number of goats =60%
The number of cows = 100%
Using ratio
Cows : Goats
60 : 100 reduced to simplest term
C:G
3:5
After
The number of cows = 100%
The number of goats = 60%
Using ratio
C:G
100:60 reduced to simplest term
C:G
5:3
Number of cows remained constant. Therefore find the common multiple.
Before
C:G
15:25
After
C:G
15:9
Find the difference in the units of goats
(a)25 - 19= 16
16 units =80
1 unit = 5
15 units (cows) = 5 x 15 = 75
There were 75 cows.
(B)
Number of goats at first
25 units = 5 x 25 = 125
Therefore percentage= 80/125 x 100
= 64%
