The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
x + 55° + 55° = 180°
x = 70°
The appropriate choice is the 2nd one:
70°
Answer:
it is a scalene triangle coz all angels are different.
To find the inverse interchange the variables and solver for y
x-1(x)= 9/7+x/7
1)4x + 2x + 3x
6x + 3x
9x
2)4(7x + 5x)={4 x 7x + (5y x 4)}
28x + 20x
48x
Answer:
6 markers
Step-by-step explanation:
5000/800 = 6.25
We can't have a quarter of a marker
If we were to round up it would have to be 5.6 km to fit 7 so we have to round down, and the answer is 6
In addition, along the 5000 m trail there will be one at 800, 1600, 2400, 3200, 4000, and 4800
We can only fit 6 of them along the trail if they are spaced 800 m apart so 6 markers will be able to fit on a 5k trail
