Hidden right triangle
28 feet tall (1 leg)
the piece that fell over is the hypotonuse
last leg is what we need to find
81-28=53
a²+b²=c²
a and b are legs and c is the hypotonuse
given
on leg is 28 and the hypotonuse is 53
th othe leg is b
28²+b²=53²
784+b²=2809
minus 784 from both sides
b²=2025
sqrt both sides
b=45
answer is 45ft
5/√11 = 5√11/√11√11 = 5√11/11
6/√8 = (2*3)/(2^3/2) = 3√2/2
√(5/7) = √35/7
Answer:
x=3
Step-by-step explanation:
We have to use the fact that all angles of a triangle add up to 180 and two supplementary angles add up to 180.
First,QRS forms a line, so angle QRT and angle TRS add up to 180 or, if we call angle TRS y for the sake of having it as a variable, 45x+y=180 or y=180-45x
Now we have all three angles of the triangle, and we know all three add up to 180, so startign with our newly found angle, (180-45x)+(25x)+(57+x)=180
180-45x+25x+57+x=180
237 - 19x = 180
57 = 19x
x=3
Let me know if you need any further explanation.
She needs 48 yards of border trims
The first step is to determine the total sum of border trims needed in feet
45 feet + 51 feet + 48 feet = 144 feet
The next step is to convert feet to yards
1 foot = 0.333333 yards
144 x 0.333333 = 48 yards
