Answer:
80 degrees
Step-by-step explanation:
Vertical angles are congruent, meaning that if a vertical angle is 80 degrees, the other vertical angle is 80 degrees; they have the same angle measure.
m < 1 = 80 degrees
<h3>
Answer: 31 degrees</h3>
This is because rotations preserve angles. The angle measures won't change. That's why angle BCD is the same as angle B'C'D'. This applies to any rotation (regardless how much you rotate), any translation, any reflection, and any dilation.
Note: dilations will change the side lengths
Answer:
Option d. the initial amount of money placed in the savings account
Step-by-step explanation:
we have

This is a exponential function of the form

where
a is the initial value
r is the growth rate
(1+r) is the base
x is the number of years
f(x) is the amount of money in a savings account
In this problem we have
a=$3,005
r=0.03=3%
(1+r)=1.03
therefore
3,005 represent the initial value ( the amount of money for the value of x equal to zero)
Answer:
x = 65
Step-by-step explanation:
Angles are equal because of the vertical angle thm
2x + 15 = 145
2x = 130
x = 65
