Answer:
75
Step-by-step explanation:
x is the exterior angle of triangle BDH, meaning that the if you add up the other two angles of triangle BDH, which are the opposite interior angles of angle x, you will get x, which is 75.
If you want to visualize the exterior angle theory, you can look at an example in the picture in this post.
Hope this answer helps you, and was deserving of a Brainiest answer. :)
The algebraic expression which can be used to represent the length of the hypotenuse (h) of an isosceles right triangle is h=x√2.
Algebraic expression are the expression which consist the variables, coefficients of variables and constants. The algebraic expression are used to represent the general problem in the mathematical way to solve them.
Steps to write down the simple algebraic expression-
An isosceles right triangle is a right triangle with congruent legs. The length of each leg is represented byx.
According to the Pythagoras theorem says that in a right angle triangle, the square of hypotenuse side is equal to the sum of square of other two legs of right angle triangle.
Let suppose the length of the hypotenuse is h. Thus, the algebraic expression can be used to represent the length of the hypotenuse is,
Hence, the algebraic expression which can be used to represent the length of the hypotenuse (h) of an isosceles right triangle is h=x√2.

To rename the number 9,200 in hundreds, we understand that '1' in thousands is equivalent to ten hundred. Hence, 9,200 divided by 100 equals 92 but 9,200 in hundreds is represented as 9200 hundreds.
Renaming the number 9,200 in hundreds means we are converting the value into groups of hundreds. Since each '1' in thousands is equal to ten hundred, we multiply the value of the thousands by ten. Therefore, 9,200 divided by one hundred is 92 and if you want to represent this number in hundreds, it would be equal to 9200 hundred.

Answer:
4x² + 20x - 2
Step-by-step explanation:
To evaluate (c ○ d)(x), substitute x = d(x) into c(x)
c(x² + 5x)
= 4(x² + 5x) - 2
= 4x² + 20x - 2
