Answer:
Your value of x will be 28°
Step-by-step explanation:
First, we'll need to find the length of the two obtuse angles. To do this, you add them together. 124 + 124 = 248°.
Since we know that the entire interior measure of the figure is 360°, you have to subtract 248 from 360 to find out the measure of the two unknown angles together.
The sum of the two unknown angles is 112°.
Now, you have to divide 112 by 4, since both of the angles multiply x by two.
112 divided by 4 is equal to 28.
This means the value of x is equal to 28°
I'll check this just to be sure. First I'll start with the top two angles:
2 x 28 = 56
56 + 56 = 112
Then I'll add it to the bottom two angles:
248 + 112 = 360°
Hi Brainiac
y= 5x-9
y= 2x+6
We need to solve y=5x-9 for y
Let's start by substitute 5x-9 for y in y=2x+6
y=2x+6
5x-9=2x+6
Add -2x to both sides
5x-9-2x=2x+6-2x
3x-9=6
Now add 9
3x-9+9= 6+9
3x=15
Now divide both sides by 3 so we find the value for x
3x/3= 15/3
x= 5
Now we have x :)
We gonna find the value for y by substitute 5 for x in y=5x-9
y=5x-9
y= 5(5)-9
y=25-9
y= 16
Final answer : x= 5 and y=16

It was my pleasured to help you :0 Good night.
Answer:
0
Step-by-step explanation:
Using the algebraic expansion
x³ + y³ = (x + y)³ - 3xy(x + y)
Given
x³ + y³ - 12xy + 64
= (x + y)³ - 3xy(x + y) - 12xy + 64
Substitute x + y = - 4 into the expression
= (- 4)³ - 3xy(- 4) - 12xy + 64
= - 64 + 12xy - 12xy + 64
= 0
Answer:
1 = 35
2 = 55
Step-by-step explanation:
so we know that between 1 and 2 it is 90 degrees we also know that angle 1 and the angel to the left of it make 180 degrees so do
180 - 90 = 90
this means the angle next to line 1 is also 90 degrees
then we would see that the 55 degrees the 90 degrees and angle 1 make 180 degrees so do
55 + 90 = 145
180 - 145 = 35 degrees so angle 1 is 35 degrees
then we would find angle 2
90 - 35 = 55 degrees so angle 2 = 55
hope this helps : )
Answer:
see explanation
Step-by-step explanation:
(6)
55° and ∠2 are vertical angles and congruent, hence
∠2 = 55°
∠1 and ∠2 are complementary angles ( They form a right angle )
∠1 = 90° - 55° = 35°
(7)
132° and ∠2 are alternate angles and congruent, hence
∠2 = 132°
∠1 and ∠2 are supplementary ( straight angle )
∠1 = 180° - 132° = 48°
