Virginia drew the figure at the right on the board. The steps below are used to solve for the unknown angle, x, in the figure bu
t are not arranged in the correct order.
1·) x= 15
2.) 75 + 15= 90
3,) 75+x= 90
4,) 75-75 + x = 90-75
Which sequence shows the correct order of the steps Virginia should follow to find the measure of the unknown
A 1234
B 3412
C 4213
D 2314
1 answer:
Answer:
Option B 3412
Step-by-step explanation:
we know that
step 1
75°+x=90° -----> by complementary angles
step 2
Solve for x
Subtract 75 both sides
75°-75°+x=90°-75°
step 3
x=15°
step 4
Verify
Substitute the value of x in the equation of the step 1
75°+15°=90°
90°=90° ----> is correct
therefore
The correct order is
3-4-1-2

Answer:
each brother received 1,015 marbles cus 2,030 divided by 2 is 1,015.
It is a function, because it has the shape of an x^2 function.
The slope would be -5 over 7
X is equal to 12 and y is equal to 8
X would represent in years by 10x
