If you would like to know which fraction (in simplest form) is equivalent to 0.42, you can find this using the following steps:
0.42 = 42/100 = 21/50
The correct result would be D. 21/50.
3/8(2x+16)-2 = 13
3(2x+16)/8-2 = 13
6x+48/8-2 = 13
6x+48-16/8 = 13
6x+48-16 = 13×8
6x+48-16 = 104
6x = 104+16-48
6x = 120-48
6x = 72
x = 72/6
x = 12
3x+2y=5
2x+2y=0
The solutions are: x=5, y=-5
The measure of the vertex angle of the isosceles Δ is 96°
Step-by-step explanation:
In the isosceles triangle
- Two sides are equal in lengths
- The angle between the two equal sides is called vertex angle
- The other two angles are called base angles
- The base angles are equal in measure
∵ The measure of one of the base angles of an isosceles Δ = 42°
- The base angles are equal in measure
∴ The measure of the other base angle = 42°
∵ The sum of the measures of the interior angles of any Δ = 180°
∴ 42 + 42 + measure of the vertex angle = 180
∴ 84 + measure of the vertex angle = 180
- Subtract 84 from both sides
∴ measure of the vertex angle = 96°
The measure of the vertex angle of the isosceles Δ is 96°
