(4x + 2) is equal to 150 because they are vertical angles. When two lines intersect, on the opposite sides of the x like these are will be equal to one another. So let’s make them equal to each other.
4x + 2 = 150
Subtract 2
4x = 148
Divide by 4
x = 37
So it will be A
17)
The two angles added up with each other
34 + 146 = 180
Since these two add up to 180 degrees, they would be supplementary angles.
So, H
18)
The two angles will make a 90 degree angle (as shown with the little box formed in the corner)
When angles add up to make 90 degrees, they will be complimentary angles.
So, C.
squaring something multiplies it by itself. -4^2 = -4*-4 = 16
What you have to do is first subtract 20 from 80 and get 60 then use the data to fill in the blanks!
Hope this helps!!!
Answer:
1. 2×3.14×80
=502.4 m
4. 90 pound on Earth weighs 34 pounds on Mars.
If it weighs 135 pounds on earth, it will weigh x pounds on Mars
=90×=135×34
=90x=4590
=x=4590÷90
x=51 pounds
So therefore it weighs 51 pounds on Mars.
Step-by-step explanation:
in question 4 you have to cross multiply
