Answer:
75
Step-by-step explanation:
at the top it says f(1)=25 which is 1 times f = 25 therefore f = 25

Answer: 20</h3>
Explanation:
For any rectangle, the diagonals are the same length.
AC = BD
7x-35 = 3x+45
7x-3x = 45+35
4x = 80
x = 80/4
x = 20
Answer:
x= 77
Step-by-step explanation:
The angle at 122 degrees is a linear pair with the isosceles triangle, meaning it makes 180 degrees.
180-122= 58 degrees
Since it is an isosceles triangle, the two angles at the bottom are both 58 degrees.
Let's use this info to find the degree at the top.
58+58= 116
There are 180 degrees in a triangle, so subtract 116 degrees we have so far to find the last angle.
180-116= 64 degrees
And since the angle at the top makes 90 degrees, we can subtract 64 degrees to find the smaller angle to the right of the 64 degree angle.
90-64= 26 degrees
And since a triangle has a total of 180 degrees, subtract the 26 degrees from 180.
180-26= 154 degrees.
And since it is an isosceles triangle, divide the remaining 154 degrees by 2 because they are both equal.
154/2= 77 degrees.
Your answer is 77 degrees.
Answer:
7/13
Step-by-step explanation:
P(A or B) = P(A) + P(B) − P(A and B)
P(red or jack) = P(red) + P(jack) − P(red and jack)
P(red or jack) = 26/52 + 4/52 − 2/52
P(red or jack) = 28/52
P(red or jack) = 7/13
