Supplementary angle = 180 degrees
angle 1 = x
angle 2 = 3x (three times the supplementary)
3x + x = 180
4x = 180
x = 45 degrees
angle 1 = 45 degrees
angle 2 = 135 degrees
Knowing that a quadratic equation has two possible solutions, we need to be careful when we solve exponential equations in checking for any quadratic one that appears. Due to 2 possible solutions,
Hope I helped :)
The base of the right triangle is 6 cm long.
The formula to find the area of a right triangle is height times base divided by 2. Therefore the formula to find the base of the right triangle using area and height is area divided by height times 2
b = (A/b) * 2
b = (33/11) * 2
b = 3 * 2
b = 6
Colder then -7.2 F would be -8.5 F
-7.2 > -8.5
anything to the left of -7.2 on the number line will be less then(oe in this case, colder then) -7.2....so -8.5 falls to the left of -7.2
