Answer:

y = 100°

Step-by-step explanation:

I can't see the full question, but I'm guessing you need to find the measure of angle y.

The total angle sum of a polygon can be calculated with the formula

T = 180°(n - 2) where T is the total angle measure, and n i the number of sides.

For our shape, there are 4 sides, so n = 4. Plug that in and simplify...

T = 180°(4 - 2)

T = 180°(2)

T = 360°

We are given 3 of the angles, so angle y is

y = 360 - 107 - 104 - 49

y = 100°

Answer:

Part 1) $\frac{a^4}{4b^2}$

Part 2) $-\frac{v^9}{w^6}$

Step-by-step explanation:

we know that

When divide exponents (or powers) with the same base, subtract the exponents

Part 1) we have

$\frac{3a^{2}b^{-4}}{12a^{-2}b^{-2}}=(\frac{3}{12})(a^{2+2})(b^{-4+2} )=\frac{1}{4}a^{4}b^{-2}=\frac{a^4}{4b^2}$

Part 2) we have

$\frac{v^3w^{-3}}{-v^{-6} w^3} =-v^{3+6}w^{-3-3}=-v^9w^{-6}=-\frac{v^9}{w^6}$

Use the zero product property to find the solution to the equation x^2 +12=7x

pochemuha

X2 + 12 = 7x x2 – 7x + 12 = 0factor the equation (x – 3 ) ( x – 4 ) = 0 Then equating both factor to 0 X – 3 = 0 X = 3 And X – 4 = 0 X = 4 So the answer is X = 3 X =4
