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:
(95/31, -118/31)
Step-by-step explanation:
-7x-8y=9
4x+9y=-22
----------------
4(-7x-8y)=4(9)
7(4x+9y)=7(-22)
-----------------------
-28x-32y=36
28x+63y=-154
-----------------------
31y=-118
y=-118/31
-7x-8(-118/31)=9
-7x+944/31=9
-7x=9-944/31
-7x=279/31-944/31
-7x=-665/31
7x=665/31
x=(665/31)/7
x=(665/31)(1/7)
x=665/217=95/31
x=95/31, y=-118/31
Step-by-step explanation:
so fill in 88 where the x is so
y = 0.9 (88) - 1
y = 78.2
