Answer:
The height is 57.5
Step-by-step explanation:
To find the height, you would use the equation h= 2 a/a+b
So you would insert the numbers and turn the equation into 2(6555/ 123+105)
Then you would solve.
After solving, you will find that H= 57.5

X/7 = 0.4 => x = 7 x 0.4 = 2.8
7/y = 0.4 => y = 7 : 0.4 = 17.5
If they are equilateral triangles, then yes; however, if they are not, it is impossible to tell without a diagram.
The two angles are corresponding angles, which means they are equal to each other. Make them equal to each other in an equation.
11x - 2 = 130
Add 2 to both sides.
11x = 132
Divide both sides by 11.
x = 12
