Take the Square root of both sides
(nearest tenth)
Look at the picture.
The angle y° and 71° are Supplementary Angles. Therefore y° + 71° = 180°.
The sum of measures of these three angles of any triangle is invariably equal to 180°.
Therefore we have the equation:
We are given the data of the minute hand traveling from 1:15 to 1:30 and a displacement of the hand by 15 cm. In this case. the arc length is the 15 cm while the angle of the sector can be derived from the clock times. The angle between <span>1:15 to 1:30 is approximately 90 degrees or pi/2. hence the radius can be computed from:
s = r theta
15 = r * pi/2
r = 9.55 cm</span>
Answer:
(y+3)^2/8^2 - (x-1)^2/6^2 = 1

Answer:
79
Step-by-step explanation:
<7=4x+1(corresponding angles)
So
3x+4+<7=180(angles on straight line)
So
3x+4+4x+1=180
7x+5=180
7x=180-5
7x=175
x=25
Now
<8=3x+4 (vertical angles)
So.
<8=3(25)+4
=75+4
=79
