Answer:

$x = 75\degree$

Step-by-step explanation:

$m\angle EFB +105\degree = 180\degree$

(linear pair angles)

$m\angle EFB = 180\degree - 105\degree$

$m\angle EFB = 75\degree$

$\because x = m\angle EFB$

(corresponding angles)

$\therefore x = 75\degree$

A. x = 2, y =6<br> B. x = 2, y =3<br> C. x =-2, y =3<br> D. x = -3, y =2

Vsevolod [243]

Answer:

the answer is

A. X=2, y=6

Step-by-step explanation:

use substitution

y= 6 so,

y-3 = 6-3 which is 3

and y-1 = 6-1 which is 5

now for x

x=2

x+3= 2+3 which is 5

2x-1= 2(2)-1

2 times 2 is 4

4-1 = 3

Sovle a triangle when A=40°, C=70°, and a=20.

Alex73 [517]

Answer: B = 70°, b = 29.2; c = 29.2

Step-by-step explanation:

sum of angles in a triangle is 180

40+70 +X = 180

X is the last angle

110+x=180

x= 180-110 =70

A= 40°

B= 70°

C= 70°

the triangle is Isosceles triangle meaning two sides are equal , angle B = angle C
