Find the value of x and y​

Mathematics
1 answer:
Alexeev081 [22]4 years ago
6 0

Answer:

x = 36 and y = 72

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

y is an external angle to the triangle on the right, thus

y = 2x

The sum of the 3 angles in a triangle = 180

Consider the triangle on the left. then

x + 2y = 180 ← substitute y = 2x

x + 4x = 180

5x = 180 ( divide both sides by 5 )

x = 36 and y = 2x = 2 × 36 = 72

Help asap Which explains how to find the quotient of the division below? -3 1/3 divided by 4/9
noname [10]

Answer:

-7\frac{1}{2}

Step-by-step explanation:

To find the quotient, convert the mixed number to an improper fraction first

-3\frac{1}{3}=-\frac{3*3+1}{3}=-\frac{10}{3}

Find the quotient now

\frac{(-10/3)}{(4/9)}=-\frac{10*9}{4*3}\\ \\=-\frac{90}{12}

Simplify

Divide by 6 both numerator and denominator

=-\frac{15}{2}=-7.5

Convert to a mixed number

-7.5=-(7+0.5)=-(7+\frac{1}{2})=-7 \frac{1}{2}
