➷ As the two lengths are a, this means it is an isosceles triangle.
The two unknown angles would be equal so we can calculate them:
(angles in a triangle equal 180 degrees)
(180 - 90) / 2 = 45
Now we can use the sine rule to calculate the length a
(6 / sin(90)) x sin(45) = a
a = 4.242640687
To one decimal place, your answer would be:
a = 4.2mm

If you would like to know which unit rate is equivalent to 17 miles per gallon, you can calculate this using the following steps:
17 miles ... x gallon = ?
51 miles ... 3 gallons
x = 17 * 3 / 51 = 1 gallon
17 miles ... x gallon = ?
34 miles ... 4 gallons
<span>x = 17 * 4 / 34 = 2 gallons</span>
The correct result would be: fifty-one miles over three gallons.
4 - 8x = -1 + 1 - 9x + 8
Combine like terms.
4 - 8x = -9x + 8
Add 9x to both sides.
4 + x = 8
Subtract 4 from both sides.
x = 4
The x-intercept is equal to 4.
