Answer:
50.32 I think
Step-by-step explanation:
52,13+50,32=102.45
Just subtract each term from the next term.
So:
2nd term minus 1st term = 0.26 - 0.36 = -0.1
3rd term minus 2nd term = 0.16 - 0.26 = -0.1
etc
So common difference is -0.1
Answer:-9 :)
Step-by-step explanation:
Answer:
<em>66°</em>
Step-by-step explanation:
mJK = ( 6x - 45 )°
mJH = ( x + 20 )°
mJK = mJH
6x - 45 = x + 20
5x = 65
x = 13
mHK = ( x + 20 )° + ( 6x - 45 )°
<em>mHK =</em> 2 × 33° = <em>66 </em>°
Answer:
15.2 cm, 130 m
Step-by-step explanation:
1. The sine of angle Z is XY/17.4; (opposite/hypotenuse);
sin(61) = XY/17.4; multiply both sides by 17.4 to find XY
17.4sin(61) = 15.2 cm
2.
This triangle is made by the anchor of the balloon to the ground, the balloon, and the area on the ground directly below the balloon.
The hypotenuse of the triangle is the 170 m string.
The angle of inclination is 50 degrees.
The height of the triangle will be opposite of the angle of inclination.
Therefore,
sin(50) = height/170 (opposite/hypotenuse)
170sin(50) = 130.2 meters
