PLEASE HELP find value of x and y

bazaltina [42]

Given : 

There is a quadrilateral.
Two sides of the quadrilateral are parallel .
Four angles are 96° , 2x° , 94° & ( 3y + 44 )°.

To Find :-

The value of x & y .

Solution :-

Here , 96° & 2x° are co - interior angles and we know that the sum of co - Interior angles is 180°.

⇒ 96° + 2x = 180° .

⇒ 2x = 180° - 96° .

⇒ 2x = 84° .

⇒ x = $\red{\sf \dfrac{84^{\circ}}{2}}$

$\bf\longmapsto x = 42^{\circ}$

Hence value of x is 42° .

Similarly , 94° & ( 3y + 44) ° are co- interior angles

⇒ 94° + ( 3y + 44)° = 180° .

⇒ ( 3y + 44 )° = 180° - 94° .

⇒ 3y + 44° = 86°.

⇒ 3y = 86° - 44° .

⇒ 3y = 42° .

⇒ y = $\sf \red{\dfrac{42^{\circ}}{3}}$

$\bf\longmapsto y = 14^{\circ}$

Hence the value of y is 14°.

WILL GIVE BRANLIEST HELP PLEASE!

I believe since you are looking for the angle of M<ABC, you just add both 120 and 25 together, since they practically share a point.

So 120 + 25 = 145

So I guess 145 would be your answer.

I remembered this type of problem from Geometry.

UNICORN A IS 15 TIMES OLDER THAN

shtirl [24]

Answer:

Unicorn A is 300 years old

Unicorn B is 20 years old

Explanation:

15x + x = 320

16x = 320

x = 20

15 * 20 + 20 = 320

Mila [183]

Answer:

A=38.88 or 38.9

Step-by-step explanation:

If both are similar then the 9 and the 7.2 are the same

9-7.2= 1.8

9x6=54

7.2-1.8=5.4

7.2x5.4=38.88 or 38.9
