Answer:
y = 50 x = 10.
Step-by-step explanation:
Let's solve for y first.
We know the line angle 80 and angle 2y-5 is on a 180 degree line.
Now we can do our work:
180 - 85 = 95
2y - 5 = 95
95 + 5 = 100
100 ÷ 2 = 50
2(50) - 5 = 95?
The equation is correct, therefore y = 50.
No we do the same thing for the other angles, 90 and 3x + 55.
Again, 180 line.
180 - 95 = 85
3x + 55 = 85
85 - 55 = 30
30 ÷ 3 = 10
3(10) + 55 = 85?
The equation is correct therefore x = 10.
Thus, y = 50 and x = 10.
Answer:
28 units
Step-by-step explanation:
First, we are going to solve the equation to find the value ^^
Let's solve the equation step by step
Step 1. Use the distributive property to destroy the parenthesis
Step 2. Subtract 196 to both sides of the equation
Step 3. Factor the expression
Step 4. Set each factor equal to zero and solve
Since we are dealing with lengths here, and lengths cannot be negative, the only valid solution is 28.
Now, we know from our problem that the missing side of the rectangle is given by the expression , so to find the actual length, we just need to replace with 8 in the given expression and simplify!
We can conclude that the missing side length represented by x + 8 units of the rectangle is 28 units.
Divide by 5, answer is 1/7
4n - 2 + 90 + 3n + 8 = 180
7n + 96 = 180
7n = 84
n = 12
