ZA and ZB are vertical angles. If m_A = (4x – 13)° and m
ZB = (3x + 19)', then find the measure of ZA.
Answers
Answer:
115 degrees
Step-by-step explanation:
Vertical angles are congruent by the vertical angles theorem.
Hence,
<A=<B
4x-13=3x+19
x=32
Substituting 32 in for x in <A
4(32)-13= 115

Answer:
22
Step-by-step explanation:
Since its a parallelogram, opposite sides are congruent. Therefore:
BC = AD
a - 1.5 = 20.5
+1.5 +1.5
a = 22
Answer:
a=22
Step-by-step explanation:
a-1. 5 =20. 5 ( opposite side of parallelogram are equal )
or, a=20. 5+1. 5
or, a=22
you can do it from another side too.
2a-20. 8 = a + 1. 2 ( opposite side of parallelogram are equal )
or, 2a - a = 1. 2 + 20. 8
or, a = 22

Find the measure of each interior angle.
Answers
Answer:
d) m<J = 115, m<K = 130, m<M = 50, m<N = 65
Step-by-step explanation:
The sum of interior angles in this rectangle is equal to 360
if we add all the given angles 7x + 10 = 360 subtract 10 from both sides
7x = 350 divide both sides by 7
x = 50 to find the measure of each angle replace x with 50
Michelle wants to make a long-term investment. She wants to triple an initial investment of
$2,000. If she invests at a simple interest rate of 12% per year, approximately how long will it
take her principal to triple?
Answers
Answer:
It will take approximately 17 years
Step-by-step explanation:
Let the initial investment be x
The investment plus the principal yields 3x
The interest is thus 3x-x = 2x
Formula for simple interest is;
I = PRT/100
R is rate = 12%
T is time = ?
x =$2,000 which is the principal
2x = x * 12 * T/100
2 = 12t/100
12t = 200
t = 200/12
t = 16.67 which is approximately 17 years

Answers
Answer: 1 by 60 units
4 by 15 units
10 by 6 units
Step-by-step explanation: Any two numbers that when multiplied together produce 60 will work.
8 times 8 is 64, and 60 times 2 is 120. So those will not work as dimensions for a rectangle with 60 square units.

Explanation:
We use the rule that

The negative exponent tells us to apply the reciprocal if we want the exponent to be positive.
In this case, a = 3 and b = 4
So,
[tex]a^{-b} = \frac{1}{a^b}\\\\3^{-4} = \frac{1}{3^4}[/tex]
which is why overall,
