It refers to the number of times a number is being multiplied by itself ... Ex: two to the fourth power
4 would be the exponent
Answer:
156 degree
Step-by-step explanation:
supplementary angle add up to 180 degree
180 - 24
= 156
Answer:
t=11
Step-by-step explanation:
31-20=11
so 11 miles left
Consider right triangle ΔABC with legs AC and BC and hypotenuse AB. Draw the altitude CD.
1. Theorem: The length of each leg of a right triangle is the geometric mean of the length of the hypotenuse and the length of the segment of the hypotenuse adjacent to that leg.
According to this theorem,

Let BC=x cm, then AD=BC=x cm and BD=AB-AD=3-x cm. Then

Take positive value x. You get

2. According to the previous theorem,

Then

Answer: 
This solution doesn't need CD=2 cm. Note that if AB=3cm and CD=2cm, then

This means that you cannot find solutions of this equation. Then CD≠2 cm.
Do the opposite of division which is multiplication. 2.6x2=5.2
I hope I did it correctly and that it benefits you ^^
