Answer:
C = 80
Step-by-step explanation:
A cyclic quadrilateral is one where all 4 vertices touch the circumference of a circle.
It has 1 interesting property that should concern you: <B + <D = 180 degrees.
3x - 59 + 2x - 1 = 180 Combine like terms
5x - 60 = 180 Add 60 to both sides.
5x = 180 + 60
5x = 240
x = 240/5
x = 48
Now go to 2x + 4.
x = 48
A = 2*48 + 4
A = 96 + 4
A = 100
So C = 180 - 100
C = 80
Fourth answer
basically the points where y=0
hope this helped
I guess c. But do check once
Answer:
(−5)(2)−2(−3)+3
CLEAR CHECK
Expression
Step-by-step explanation:
We have to wright 100,000 using exponents. The exponent of number shows how many times you use the number in multiplication.
For example: 64 = 8², because: 64 = 8 · 8or: 64 = 4³, because 64 = 4 · 4 · 4 In this case:100,000 = 10 · 10 · 10 · 10 · 10Therefore:100,000 = 10^5 ( or "10 to the fifth power" )Answer: 10^5.
