The value of 4b/a is 240.
Step-by-step explanation:
Given,
a x 60 = b
or
b = a x 60
Similarly, the value of a would be:
We need to find
Therefore, we have to put the either values of a and b in the specified equation:
Hence,
We have only put the value of one variable to evaluate or to make it variable free
or
Therefore, the value of 4b/a is 240.
Answer:
Step-by-step explanation:
The area of an isoceles triangle is:
A = base x height / 2
The base is the unequal side in the isosceles triangle. You have to calculate the height using the Pythagorean Theorem.
Since two side are equal in length, if you draw a vertical lined from where these two sides meet and bisect the base, you will create two right triangles.
So a² + b² = c² where c is the hypotenuse of the right triangle. This hypotenuse is also the two equal sides of the isosceles triangle. They told you the length of the base but you need to divide that in half since your line bisected the base.
So now you know one side of the right triangle is 8cm which is half of 16cm. You also know the hypotenuse is 17cm. Solve the Pythagorean Theorem for the other side and that will give you the height of your bisecting line.
8² + b² = 17² OR 64 + b² = 289
Solve for b
b² = 289 - 64 OR b² = 225 and finally b = which is 15
So now you can calculate the area of the triangle:
A = 16 x 15 / 2 or 240 / 2 which is 120
So the area is 120 cm²
The correct answer is: [B]: " y = (-⅓)x + 6 " .
