Answer:
jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct
Step-by-step explanation:
so, all angles of a triangle have to add up to 180;
(15x) + (8x - 11) + (3x + 9) = 180
15x + 8x - 11 + 3x + 9 = 180
add your common numbers
26x - 2 = 180
add 2
26x = 182
divide 26
x = 7
put it back into the equation
15(7) + 8(7) - 11 + 3(7) + 9 = 180
180 = 180
Answer:
4/5
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A right angled triangle with sides as 3 , 4 and 5 cm .
We need to find the value of sin(β) in the given triangle . We know that the ratio of sine is ,
sin(β) = p/h
- Where p is perpendicular and h is hypontenuse.
sin(β) = 4/5
<h3>Hence the required answer is 4/5.</h3>
Answer:
627 pounds
Step-by-step explanation:
Distance formula: d= square root of (x2-x1)^2+(y2-y1)^2
(3,5) (7,3)
d= square root of (7-3)^2+(3-5)^2
d= square root of (4^2)+(-2^2)
d= square root of 16+4
d= square root of 20
d=4.47...rounded= 4.5
Hope this helped!
