To find angle Y, take 180 degrees (linear pair) minus 35 degrees (angle X).
180-35=145 degrees
Angle Y=145 degrees
Angle W is also 145 degrees since it’s a vertical angle to Angle Y.
To find angle N, take 90 degrees (complementary angle) minus 55 degrees (angle M).
90-55=35 degrees
Angle N=35 degrees
Hope this helped!

Answer:

$7\sqrt{2}$

Step-by-step explanation:

We know that the missing angle is 45 degrees and the hypotenuse is 14.

If both side angles equal to 45, according to base angle theorem, this triangle is isosceles.

Since this triangle is isosceles, the two legs must be equal. Let x be the legs.

According to the 45 45 90 triangle theorem, the hypotenuse is equal to $\sqrt2$ *x

If 14 = $\sqrt{2}*x$

$\frac{14}{\sqrt{2} }$ = x

Rationalize denominator

$x = \frac{14}{\sqrt{2} } * \frac{\sqrt{2} }{\sqrt{2} } = \frac{14\sqrt{2} }{2} = 7\sqrt{2}$

The answer is $7\sqrt{2}$

Hope this helps :)

Solve 2w^2– 16w = 12W – 48 by factoring. Select the solution(s)

UkoKoshka [18]

Answer:

w=12 or w=2

Step-by-step explanation:

2w^2-16w=12w-48

2w^2-28w=-48

2w^2-28w+48=0

2(w^2-14w+24)=0

2(w-12)(w-2)=0

(w-12)(w-2)=0

w=12 or w=2

3. Which expression is equivalent to the expression shown below?

chubhunter [2.5K]

Answer:

option a

Step-by-step explanation:

we have:

7/2x-3(5x-1/2)

apply distributive property we have:

7/2x-3*5x-3*(-1/2)

7/2x-15x+3/2

7/2-15=-23/2

so we have:

-23/2x+3/2
