Hello from MrBillDoesMath!
Answer:
45 (all three: 45, 45, 90)
Discussion:
Let "x" be the base angle in the isosceles triangle. As base angles are equal in an isosceles triangle and a triangle contains 180 degrees:
x + x + 90 = 180 =>
2x + 90 = 180 => subtract 90 from both sides
2x = 180 -90 =>
2x = 90 => divide both sides by 2
x = 45
Thank you,
MrB
Answer:
2.25
Step-by-step explanation:
The question gives us one hint. That side of the square is 1.5"
Because it gives us that, we can use that to find the area. Because it is a square, all of the sides are the same length.
To find the area it is basexheight
So that is why the answer is 2.25 because 1.5x1.5=the area of the square
Answer:
15 scarves
Step-by-step explanation:
CROSS MULTIPLICATION METHOD
5 YARDS = x
⅓ YARDS = 1 scarves
⅓x = 5
x = 5×3
x = 15
