The answer is y = 14
Explanation:
AC≅CB, so the triangle is isosceles
So, m∠A = m∠B
m∠A = 50 and m∠A = m∠B, so m∠B = 2x = 50
The sum of all angles in a triangle is 180°
So:
180 = (5y + 10) + 50 + 50
180 = 5y + 10 + 100
180 = 5y + 110
-5y = 110 - 180
-5y = -70
5y = 70
y = 70/5
y = 14
Hope it helps!
Hello :
x²-8x+15 = (x-3)(x-5)
<span>h(x) = f(x) ÷g(x) = (x-3)(x-5)/(x-3)= x-5</span>
Answer:
Steps involved in finding the value of x calculator is as follows:
Method 1: The required input value must be entered in the divisor and the product field.
Method 2: Click the ‘SOLVE’ option to obtain the output.
Method 3: The output field will present the x value or the dividend.
In 1st fig
A=5×x(let)
9=5×x
in 2nd fig
A=10×2x(5 is doubled so ×also doubled)
A=10×2×9÷5
A=36
The answer is 27,904,000.
Explanation: 100 divided by 14 = 7.1 and I rounded that to 7, so I multiplied 218,000 by 2 then doubled each number so it went from 218,000 to 436,000 to 872,000 etc.
