Answer: 4x + x = 35 or 5x = 35
Step-by-step explanation:
Let the short side of triangle is x unit,
Thus, According to the question,
The other longer sides are 2x and 2x,
Thus, the perimeter of the isosceles triangle = 2(2x) + x = 4x + x
But, the perimeter of the triangle = 35 inches,
⇒ 4x + x = 35
⇒ 5x = 35
⇒ x = 7
Therefore, the measurement longer sides of the triangle = 2x = 2×7 = 14 inches
And the measurement of the shorter side = x = 7 inches
Answer:
25/64
Step-by-step explanation:
C=πd
find diameter:
small= 15 x 15= 225
large= 24 x 24= 576
multiply:
225 x 3.14= 706.5
576 x 3.14= 1808.64
ratio:
706.5/1808.64
reduce:
25/64
C = 71 degrees
b = about 8.70 (8.7)
c = about 15.43
C: All the angles in a triangle add up to 180 degrees. So, to find "C", you add together "A" and "B" (69 and 40) and subtract their total from 180. This will give you C = 71 degrees.
Now we will solve for "b"and "c". When solving for a side angle, you use the following system; a/SinA = b/SinB = c/SinC.
b: Since we can fill in for a/SinA, and the Sin B b/SinB we will use that to solve for "b". Filling in for each know part, you'll get 15/69 = c/71. Next you multiply 15 and 71, then divide by 69 to get b. 15*71 = 1,065. 1,065/69 = 15.4347... which rounded equals 15.43.
c: Using the same steps as "b", we will now find "c". 15/69 = b/40. Multiply 15 and 40, then divide by 69. 15*40 = 600. 600/69 = 8.6956... which rounded equals 8.70 or 8.7.
I hope this helps!
