Answer:x=27
Step-by-step explanation:
Hi there!
Since we know that this is a right isosceles triangle, we can use the 45-45-90 relationship to figure out the missing side lengths. Using this relationship, we know that the two marked sides are both equal to 5 inches. Next, we need to use the formula to find the area of a triangle, which is A = 1/2(b * h). We know that the base of this triangle is 5, as is the height. All we need to do is plug in the numbers and solve: A = 1/2(5 * 5) | A = 1/2(25) | A = 12.5 inches^2.
Hope this helps!! :)

Answer: a. 1/6. b. 2/3. c. 5/6
Step-by-step explanation:
Number of adults randomly selected= 6
a. Finding the probability of adults that have cheated on an examination before is exactly 4.
The numbers are 1, 2, 3, 4, 5 and 6.
Probability of chosen exactly 4 will be 1/6 since 4 can only occur once.
b. More than 2means 3,4, 5 and 6.
Probability that the number of adults that have cheated on a test or exam is more than 2 will be:
4/6 = 2/3
c. At most 5 means 1,2,3,4 or 5
This will give 5/6
Answer:
the answer is 29
Step-by-step explanation:
a^2 + b^2 = c^2 (btw ^ means to the power)
a and b are the legs. c is the hypotenuse
21^2 + 20^2 = c^2
441 + 400 = 481
then we have to square it.
the square root of 481= 29.
btw the hypotenuse is always going to be bigger than the legs.
hope it helps!! btw it is right!
