Answer:

The measure of Angle G is 62.5°.

Step-by-step explanation:

Given:

Δ EFG is an Isosceles Triangle.

EG = EF

m∠ E = 55°

To Find:

m∠ G = ?

Solution:

Δ EFG is an Isosceles Triangle. ........Given

EG = EF                                   ..............Given

∠ G = ∠ F = x (say)              ..................Isosceles triangle property

Now in Δ EFG we have

∠ E + ∠ G + ∠ F = 180° .......... Angle sum property of triangle

On substituting the values we get

55 + x +x =180\\\\2x=180-55\\\\2x=125\\\\\therefore x=\frac{125}{2} =62.5\°\\\\\therefore x=62.5\°

The measure of Angle G is 62.5°.

Solve the equation: <br> 8y - 3 = бу + 17
balandron [24]

Hey!

------------------------------------------------

Steps To Solve:

8y - 3 = бу + 17

~Subtract 8y to both sides

8y - 3 - 8y = бу + 17 - 8y

~Simplify

-3 = -2y + 17

~Subtract 17 to both sides

-3 - 17 = -2y + 17 - 17

~Simplify

-20 = -2y

~Divide -2 to both sides

-20/-2 = -2y/-2

~Simplify

10 = y

------------------------------------------------

Hence, the answer is \Large\boxed{\mathsf{y~=~10}}

------------------------------------------------

Help if you know thanks
Yanka [14]

Answer:

x = -1/2  x=-1

Step-by-step explanation:

2x( x+1.5) = -1

Distribute

2x^2 + 3x = -1

Add 1 to each side

2x^2 +3x+1 = 0

Factor

(2x+1) (x+1) =0

Using the zero product property

2x+1 = 0   x+1=0

2x = -1    x=-1

x = -1/2  x=-1
