Answer:
c = 36.06
Step-by-step explanation:
a² + b² = c²
20² + 30² = c²
400 + 900 = c²
c² = 1300
c = 36.06
Answer: Maybe 5.7
Step-by-step explanation: To solve this we are going to need to understand the pythagorean theorem. we can use it as a way to find this certain side. if we put these numbers in the theorem, we get a^2+49=81 (7^2=49 and 9^2=81), we can subtract 49 on both sides and get 32. We would also need to take out the power of 2 on the side of the a^2, so you would do the square root of a^2, which would just become a and the square root of 32, which if you crunch the numbers on a calculator. You would get 5.656..... then you round it to the nearest tenth and get 5.7.
Answer:
18900 watt-hours
Step-by-step explanation:
3600 x 24 (hours in a day) = 150
150 x 6 (hours) = 900
3600 (watt hours per day) x 5 (days) = 18000
18000 x 900 = 18900
total= 18900

5. ? what graphs
Answer:
AB is congruent is CD. (Last one)
Step-by-step explanation:
Hypotenuse leg is when the hypotenuse and ONE (you only need one, not two) leg of the triangle are congruent in a RIGHT triangle.
In the image, you already know that it is a right triangle and you know that the hypotenuse are congruent (Reflexive Prop) .You just need to know that the legs are congruent. So you choose which one has the legs congruent. The leg pairs that can be congruent are AD and CB or DC and AB. The only one that matches this is the last one
