Answer:
130 degrees
Step-by-step explanation:
let the angle be x
2x+45+55=360(Sum of angles in quad)
2x=260
x=130
Answer:
The line AB, with A(Ax, Ay), B(Bx, By) and midpoint M(Mx, My) satisfying:
Ax + Bx = 2Mx
Ay + By = 2My
=>
2 + Bx = 2*1
5 + By = 2*2
=> Bx = 0
=> By = -1
=> B(0, -1)
Hope this helps!

Answer:
<A= 47, <B= 90, <C= 43
Step-by-step explanation:
2x +3 + 4x + 2 + 2x-1 = 180
8x + 4= 180
8x = 176
x =22
2x+3= 44+3= 47
4x+2 = 88+2 = 90
2x-1= 44-1 = 43
Answer: 5500cm.
Step-by-step explanation:
A revolution corresponds to circumference of the bicycle wheel.
The radius of the circle = 70/2 since two radii makes a diameter.
Therefore r = 35cm
Circumference of a circle = 2πr or πd where π = 3.142 or 22/7
We now have = 2 x 22/7 x 35
Therefore 0ne revolution = 220cm.
Therefore, the distance traveled by making 25 revolution
= 220 x 25
= 22000/4
= 5500cm.
