Answer:
m∠Z1 = 93°
Step-by-step explanation:
Vertical Angles are the angles opposite each other when two lines cross.
They are congruent (the same as each other).
Therefore, m∠Z1 = m∠Z2, so if m∠Z2 = 93° then m∠Z1 = 93°
The measure of ∠1 is 93 degrees
What are vertical angles ?
Vertical angles are a pair of opposite angles formed by intersecting lines. Vertical angles are opposite each other and they share the same vertex point.
Vertical angles are always congruent.
Therefore, since ∠1 and ∠2 are vertically opposite angles this means they are congruent.
Therefore,
∠1 ≅ ∠2
∠2 = 93°
∠1 = 93°

Solve it please with explanation Marty simplified the expression 2(x - 2) - 2(3) as 2x - 8. Is he correct? Explain why or why not.
Answer: Marty is not correct
Step-by-step explanation:
2(x-2)-2(3) use distributive property
2x-4-6
2x-10
Marty is not correct
Answer:
Marty is incorrect.Step-by-step explanation:
Let's check his work by simplifying the given expression.
2(x - 2) - 2(3)=> 2x - 4 - 6=> 2x - 10When I compare Marty's result and this result, they are un-equal. Hence, Marty is incorrect.
Marty's mistake
Marty must've got the problem wrong because of not understanding the distributive property.He probably forgot to multiply -2 by 2. Instead, he only subtracted 2 when he should've subtracted 4 from 2x.How many triangles are in the accompanying figure?

10. In the figure, m angle1 = (8x + 7)º, m Angle2 = (4x + 14),
and m angle4 = (13x + 12)°. Your friend incorrectly
says that m angle4 = 51°. What is m Angle4? What
mistake might your friend have made?
Corresponding angles are congruent, and they have equal measure
The value of angle 4 is 129 degreesYour friend used the wrong theoremHow to determine the value of angle 4From the figure, we have:
Angle 4 = Angle 1 + Angle 2
So, the equation becomes
13x + 12 = 8x + 7 + 4x + 14
Collect like terms
13x - 8x - 4x = 7 + 14 - 12
Evaluate the like terms
x = 9
From the question, we have:
Angle 4 =13x + 12
So, we have:
Angle 4 = 13 * 9 + 12
Evaluate
Angle 4 = 129
Hence, the value of angle 4 is 129 degrees

What value of b will make the expressions −12.8x+b and −3.2(4x−2.1)+2.4 equivalent?
Solution:
Note that:
[tex]-12.8x+b = -3.2(4x-2.1)+2.4[/tex]
Simplifying the distributive property.
[tex]-12.8x+b = -3.2(4x-2.1)+2.4[/tex]
[tex]-12.8x+b = -12.8x + 6.72+2.4\\[/tex]
Simplifying the RHS.
[tex]-12.8x+b = -12.8x + 9.12[/tex]
Canceling out -12.8x.

The 11th term of an arithmetic sequence is 32 and the sum of the first 11 terms is 187. Calculate the 21st term of the sequence.
Answer:
62
Step-by-step explanation:
The general term of an arithmetic sequence with first term a1 and common difference d is ...
an = a1 +d(n -1)
The sum of n terms of an arithmetic sequence is ...
Sn = (2·a1 +d(n -1))(n/2)
Using these relations and the given values of a11 and s11, we can find a1 and d:
a11 = a1 +d(11 -1) = 32
S11 = (2·a1 +d(11 -1))(11/2) = 187
These simplify to ...
a1 +10d = 32
2a1 +10d = 34 . . . . multiply the second equation by 2/11
__
Subtracting the first of these from the second, we get ...
a1 = 2
Then the common difference is ...
d = (32 -2)10 = 3
And the 21st term is ...
a21 = 2 +3(21 -1) = 62
The 21st term is 62.
