4x+1+57=90
4x+58=90
4x=32
X=8
x = 85 degrees and
y = 45 degrees.
Step-by-step explanation:
Step 1:
The angle for a straight line is 180°. The sum of the angles in a triangle is 180°. These two statements are required to solve this problem.
The angles of x° and 95° are on a single straight line.
So 

So the angle of x is 85°.
Step 2:
The sum of the angles in a triangle is 180°.
So 


So the angle of y is 45°.
Answer:
The slope of line t is -4/5.
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(14-10)/(2-7)
m=4/-5
Parallel lines have same slopes.

Answer:
28.26
Step-by-step explanation:
This is the formula for area of a circle
A = pi r^2
Substitute the given values
A = 3.14 (3)^2
A = 3.14 (9)
