Answer:
angle 3. ( x ) is 136°
angle 4 ( y ) is 44° !!
Step-by-step explanation:
Let angle 3 be x and angle 4 be y
Given, Angle 3 and angle 4 form a linear pair
x + y = 180 [ sum of linear pair angle is 180 ] ... ( i )
Also, The measure of Angle 3 is four more than three
The measure of Angle 3 is four more than threetimes the measure of angle 4.
x = 4 + 3y .... ( ii )
Putting value of x from ( ii ) in ( i )
4 + 3y + y = 180
4y = 176
y = 44
Also, x + y = 180 => x = 180 - 44 = 136
Answer:
x = 2 + sqrt(5) or x = 2 - sqrt(5)
Step-by-step explanation using the quadratic formula:
Solve for x over the real numbers:
7 (x^2 - 4 x - 1) = 0
Divide both sides by 7:
x^2 - 4 x - 1 = 0
Add 1 to both sides:
x^2 - 4 x = 1
Add 4 to both sides:
x^2 - 4 x + 4 = 5
Write the left hand side as a square:
(x - 2)^2 = 5
Take the square root of both sides:
x - 2 = sqrt(5) or x - 2 = -sqrt(5)
Add 2 to both sides:
x = 2 + sqrt(5) or x - 2 = -sqrt(5)
Add 2 to both sides:
Answer: x = 2 + sqrt(5) or x = 2 - sqrt(5)
Simply divide 23 and 2/5 bags of apples between 9 friends:
23 and 2/5 bags ÷ 9 friends= 117/5 bags ÷ 9 friends
= 13/5 bags
= 2 and 3/5 bags
Therefore, each friend receives 2 and 3/5 bags of apples.
Hope this helps!
3 + 3 + 1 = 7
3 + 3 are the double ones
+1
=7
Answer:
They're both acute
Step-by-step explanation:
They both meausre less than 90°
A right angle would look like an L (it could be a flip L as well)
And an obtuse angle is anything bigger than a right angle
