Answer:
The length of each side of the square is 5 meters
Step-by-step explanation:
<u><em>The correct question is</em></u>
A figure is formed by a square and a triangle. total area is 32.5 m^2. the area of the triangle is 7.5 m^2. what is the length of each side of the square?
we know that
The total area of the figure is equal to the area of triangle plus the area of square
so
The area of square is equal to the area f the figure minus the area of triangle
Let
A ----area of the square
Find the length side of the square
Remember that the area of the square is
where
b is the length side of the square
substitute
square root both sides
therefore
The length of each side of the square is 5 meters
Answer:
x =1 and y=-1
Step-by-step explanation:
2x - 3y=-1
x-y=1
there for ok there is a lot of steps i had to do so ill take a pic of it
and the big one is the first one
Answer:
38°
Step-by-step explanation:
The sum of angles that make a line is 180°; the sum of angles in a triangle is 180°. So, we have the following relations:
2x +y +A = 180
2y +x + B = 180
A +B +33 = 180
Adding the first two equations and subtracting the third, we get ...
(2x +y +A) +(2y +x +B) -(A +B +33) = 180 +180 -180
3x +3y -33 = 180
x + y - 11 = 60
x + y = 71
__
We know vertical angles are congruent, so in triangle QRK, we have ...
2y +2x +∠K = 180
∠K = 180 -2x -2y = 180 -2(x +y) = 180 -2(71)
∠JKL = 38°

Answer:
228 inches
Step-by-step explanation:
The scale is 12 inches : 5 yards, that means
Real Life 5 yards is 12 inches in drawing.
This is a ratio
We can write:
Now we can create another ratio where drawing length is "x" and real length is 95 yards.
<u>Note:</u> remember to keep yards on numerator and inches on bottom
So, we can write:
We can equate these 2 ratios and cross multiply and solve for x:
Hence 95 yards would be equal to 228 inches in the drawing
