Answer: 41.0 for the 1st question. 50.0 for the 2nd question.
Oki soooo, in the first sum we know that it is a right angle triangle from that square thingy on the corner of the triangle. The missing side that we are told to find is known as the hypotenuse. Whenever there is a right angle in a triangle with two side lengths given except the hypotenuse side; always remember to use the pythagorean theorem!
In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides. And it's formula is:
c^2 = a^2 + b^2
Where c is the hypotenuse side, a is one of the side length except the hypotenuse and b is the remaining side length except the hypotenuse and the length that you already use for a. Now let's place the value! >:)
c^2 = a^2 + b^2
c^2 = 9^2 + 40^2
c^2 = 81 + 1600
c = square root of 1681
c = 41
Since c was the hypotenuse and this is what the question wanted from you U_U! To 1 decimal place would be 41.0
~`*^! Now for the 2nd question, the question asks for hypotenuse again so place the values by yourself and try doing it yourself to see if your correct! Scroll down to see if what you did was correct or not! Only then you can make sure that you understood on how to do this! And make sure to remember the formula: c^2 = a^2 + b^2
c^2 = a^2 + b^2
c^2 = 30^2 + 40^2
c^2 = 900 + 1600
c = square root of 2500
c = 50
As decimal, 50.0
Congrats if you made it right! And by any chance it gets wrong then make sure to visit Khan Academy for better tutorials or might even ask tutors in Brainly!
Brainliest pweasee if the answer is clear and correct! <3 ~ ~ ~ ~ ~ ~ ~ ~ ~
