Answer:
17° and 73°
Step-by-step explanation:
For two complementary angles, the sum of angles is equal to 90 degrees.
Let other angles = x
First angle = 5+4x ...(1)
ATQ,
5+4x+x=90 ...(2)
Equation (1) and (2) shows the equations for the given problems.
5+5x=90
5x = 85
x = 17°
Other angle = 17
First angle = 5+4x
= 5+4(17)
= 73°
So, the other two angles are 17° and 73° respectively.
Answer:
a= 3/11
b = 2/11
Step-by-step explanation:
a(1) + b(4) = 1
a + 4b = 1
a(3) + b(1) = 1
3a + b = 1
b = 1-3a
a + 4(1-3a) = 1
a+ 4-12a = 1
-11a = -3
a = 3/11
b = 1-3(3/11)
b= 2/11
Answer: Student X and Y
Step-by-step explanation:
Student W started off correctly as they simplified the first expression and got rid of the parentheses.
Student Z also started off correctly as they simplified the second expression and combined the like terms.
I don’t see what students X and Y did as their first step but I hope this helps. Sorry if it doesn’t
